Pastel drawing - Egyptian Mau cat
1) In this tutorial I will tell you how to draw an Egyptian Mau cat. These are very beautiful cats with large green currant or yellow-amber eyes. The Egyptian Mau has a wonderful and unique color. This is their distinctive feature. For this picture we need a dark blue A4 pastel sheet. Draw a sketch with a white, well-sharpened pastel pencil.
2) Let's move on to drawing the eyes and nose. For the eyes, use green, yellow, dark orange, black pastel pencils. Carefully shade the eye, make the pupil black, at the end add highlights with a white pastel pencil. For the nose, use white, pink, black, red pastel pencils. Shade around the eyes and nose with a light white pencil and rub with your finger. When drawing such small details, your pencils should be sharpened well!
3) Shade the ear first with a pink pastel pencil, and on top with a white pastel pencil. Rub everything with your finger. Add black shades and rub. Now sharpen a good white pastel pencil and draw white hairs in quick and light strokes.
4) Shade the cat's head with white and gray pastel pencil. Somewhere you can add a few strokes of blue. After that, rub everything with your finger.
5) We begin to clarify the details. With a white pencil, imitate the growth of wool with small strokes. Draw the stripes with small strokes of black.

Please draw me a sea
So that quiet waves flicker
So that the smells of happiness and will
My chest was filled to the brim.
Draw sand under my feet
Yellow-yellow, like a ray of sunshine.
And decorate the sky with all the clouds
Don't just draw clouds, please.
Draw me a kite
For the wind to play rebellious with him.
So that I, having nothing,
She continued to be kind and gentle.
Will you draw me the sea and the sky?
And will you sit on it with clouds?
Will you paint me an eternal summer?
And sand under your bare feet?
Draw, but don't put a full stop
I didn't tell you about the main thing,
Please draw me a daughter
And draw yourself at the pier.

How to paint a picture with paints
Pick up watercolors. They are the easiest way to start painting a picture. They can convey all shades and give brightness when translucent. Choose whether you want to paint on a wet or dry surface. When painting on a wet surface, the outlines of objects are blurred, which is useful in landscape compositions or when filling vegetables and fruits in the background.
Take a drawing paper - it does not swell from excess water, and the places that need to be corrected can be easily washed off with foam rubber. Place the paper at a 30-40 degree tilt to spread the paint evenly.
Sketch the main objects in pencil. If this is a still life, then determine the location of the table or other surface and fruit and vegetable composition. If this is a portrait, then take into account the proportions of a person, and if it is a landscape, then light sketches will be enough here - colors will play the main role. When painting with paints, especially watercolors, take into account the fact that you need to think over the shade of each stroke in advance. The only way to correct the error is to use wet foam rubber. Then apply the desired strokes on an already well-dried surface.
Draw the general background with foam rubber or a wide squirrel brush. When painting large areas, be sure to have enough paint on the brush. Apply the background from light to dark. Please note that the effect of white when painting with watercolors is achieved only at the expense of unpainted or well-washed places. Be careful not to tear or roll the paper.
Determine the sunny side and shaded areas of the painting. Starting from this, sketch out all the objects. Mix colors on the palette - in the picture, overlapping color layers can lead to simple color distortion in dark shades. Apply each next stroke next to the previous one with a slightly dampened brush for a smooth transition.
Painted paintings have the gift of drawing attention to themselves again and again. The unique play of shades allows you to convey everything to the smallest detail. But how exactly to paint a picture with paints? - drawing Whatman paper,

Draw the details of the daffodil more precisely. From each vertex of the hexagon, draw straight lines that converge towards the middle. These lines will be the vertical axes for the flower petals. Draw midpoints for the lines. Now draw strokes from each vertex, expanding to the indicated points. Next, bring the strokes to the middle of the flower in the form of straight parallel lines.
In order to draw a daffodil, draw the petals of the flower with smooth lines - smooth out the main outlines. Draw a slight curl of the petals with wavy lines along their walls. Draw the middle of the daffodil. First, make the borders of the oval jagged with a small step. Draw a small dome on the right side of the oval, making the middle more voluminous.
Draw part of the stem of the daffodil in the form of a tubular arc connecting the flower itself and the straight, thin stem with the wide side directed towards the petals. Draw the leaf of the plant as an elongated, narrow one with a pointed apex.
Sketch the flower with a simple pencil. Shade the middle of the daffodil tightly with straight thin lines extending from the middle to the borders of the oval. Draw rays along the vertical center line on the petals. Shade both the left side of the stem and the top of the daffodil leaf.
Sketch the flower itself in yellow. Make the middle a tone darker. Sketch the leaf and stem in an even green tone.
Narcissus is one of the first spring flowers. So gentle and at the same time strict, unapproachable, noticing only his own beauty. Such beauty can be kept for a long time only on a piece of paper. - landscape sheet;

How to draw an anchor
Draw a modern anchor design with two sharp edges at the bottom. Draw a vertical line in the middle of the sheet, narrowed slightly at the top and widened at the bottom. This will be the anchor spindle. Draw a circle around the upper border of the spindle, the so-called. eye - the place of attachment of the cable or rope for raising or lowering the anchor. At the top of the vertical, draw a horizontal line - the stock. Secure the lower part of the spindle with a large tick.
Draw the individual parts of the anchor in more detail. Draw the spindle in the form of two straight lines, each of which at the bottom draw out in different directions, forming an anchor, its main part. This way you get two anchor horns. The joints of the lines should be smooth. Make each horn three-dimensional by adding another line following the outline of the anchor. At the tips of the horns, depict the lobes - wide plates with sharp outer tops. Note that the heel of the anchor should be sharp enough.
Draw the details of the stock. From an inclined straight line at a short distance, draw another one with the same slope, but slightly convex, thus delimiting the lateral and lower parts of the stem. Connect both lines with a few vertical strokes. Now draw another oblique line repeating the outlines and continue vertical strokes at an angle of slightly more than 90 degrees. Draw a neck above the upper border of the stem - draw a small rectangle and divide it in half with a vertical line. Make the eye ring double.
Darken individual sections of the anchor: the lower part of the lopa and the right horn. Shade the stock with short lines and the neck, its right part. Also darken the part of the spindle that goes along the right border of the vertical - the drawn anchor is ready.
An anchor is a special metal structure designed to secure a ship in one place. It has many different types, but the base is always the same - a heavy bottom, which is fixed on a straight metal vertical. The drawn anchor is most often used as a nautical symbol. - landscape sheet;

Sometimes it becomes necessary to do an elementary thing, while it turns out that we do not know how to do it. For example, how to draw a rhombus. In fact, everything is very simple.
In this article, you will learn how to draw a rhombus correctly, and what kind of geometric shape it is.
What is a rhombus?
A rhombus is a kind of parallelogram, the peculiarity of which is that the opposite sides of this figure are parallel to each other, and in a rhombus they are also equal to each other. The definition of a rhombus to the general form of a parallelogram is indicated by the fact that opposite angles are equal.
How to draw a rhombus
There are several ways to draw a shape such as a rhombus. In this article, we'll walk you through two easy ways.
For the first method, we need: a pen or pencil, an eraser, a sheet in a cage from a school notebook, a ruler or any straight object similar to it, if the exact dimensions of the rhombus are not important.
- So, first, let's draw a point at one of the intersections of the cell lines. Better, of course, to place the point not too close to the edges. Determine the size of the figure.
- Further, from the midpoint, we count the required number of cells to the left (or right) and put another point. In the opposite side, through the same number of cells, draw a third point. Now we do the same up and down. The sequence does not matter, the main thing here is to count the same distance from the midpoint to the left and to the right and separately up and down. That is, if four cells are counted to the right, and six cells are counted up, respectively, four cells to the left, six cells down.
- We connect with a ruler or any other suitable object all the points to each other, except for the middle one. The midpoint can be erased with an eraser if you used a pencil. The rhombus is ready.
The second method is similar to the first, but we will draw on blank paper without cells. For this we need: a pencil and / or a pen, an eraser, a blank sheet of paper, a ruler and a square (or any object with a right angle).

Embossed knitting patterns - this is an alternation when knitting front and back loops, while the fabric is three-dimensional due to the combination of convex and concave sections, and also quite dense (without gaps), therefore such patterns are especially expressive. There are a great many relief patterns, they differ in small or large rapport. These patterns are ideal for smooth cotton, cotton / rayon, silk and linen blended yarns. If the yarn is thick, then the pattern looks especially embossed, and if it is thin, then you get an exquisite, noble structure. Embossed patterns are quite simple to knit, therefore they are recommended for beginners, because help them gain skill and experience. Confident knitters also do not ignore embossed patterns, because they are convenient to combine with openwork and give it a special elegance. So that the charm of the relief patterns does not disappear, they should not be ironed and treated with steam, it is enough to moisten and allow to dry in a straightened form.

A rhombus is a simple geometric figure with four vertices and therefore is one of the special cases of a parallelogram. It is distinguished from other polygons of this kind by the equality of the lengths of all sides. This feature also determines that the angles at the opposite vertices of the figure are of the same magnitude. There are several ways to construct a rhombus - for example, using a compass.
You will need
- Sheet, pencil, compasses, ruler, protractor.
Instructions
- Put two arbitrary points on opposite edges of the sheet, which will be opposite vertices of the rhombus, and designate them with the letters A and C.
- Place an auxiliary point approximately where the third vertex of the shape should be. The distance from it to vertices A and C should be the same, but you do not need to be absolutely precise at this step.
- Measure the distance from point A to the auxiliary point with a compass and draw a semicircle centered at point A, facing towards point C.
- Draw the same semicircle (without changing the distance plotted on the compass), centered at point C and directed towards point A.
- Place points B and D at the top and bottom intersections of the semicircles and draw connecting lines between points A and B, B and C, C and D, D and A. This completes the construction of a rhombus with an arbitrary side and corners.
- If you want to build a rhombus with a given length of sides, then first set aside this value on the compass. Then place point A, which will be one of the vertices of the quadrilateral, and draw a semicircle in the direction of the intended opposite vertex.
- Place point C where you would like to see the opposite vertex. Proceed from the fact that the distance from the outlined semicircle to this vertex should be less than the distance laid down on the compass. The smaller this distance is, the wider the rhombus will be.
- Repeat steps 5 and 6. After that, the construction of a rhombus with sides of a given length will be completed.
- If you want to build a rhombus with a given angle, then first mark with arbitrary points A and B two adjacent vertices of the rhombus and connect them with a segment.
- Set aside the length of the segment AB on the compass and draw a semicircle centered at point A. All subsequent constructions are carried out without changing the distance laid out on the compass.
- Attach the protractor to line segment AB so that the zero line coincides with point A, measure the given angle and set an auxiliary point.
- Draw a straight line segment starting at point A, passing through the construction point, and ending at the semicircle you sketched earlier. Mark the end point of the line with the letter D.
- Draw two semicircles directed towards each other with centers at points B and D. One of the intersection points of the semicircles will be the already existing point A, and the other will be marked with the letter C and connect it to points B and D. This completes the construction of a rhombus with a given angle.

Defining a rhombus as a geometric shape
A rhombus is a parallelogram in which all sides are equal. If the rhombus has right angles, then it is called a square.
The term "Rhombus" itself, translated from Greek, means "tambourine". Of course, in our understanding, a tambourine, as a musical instrument, has a round shape. But now tambourines are made round, and in ancient times it just had a square or rhombus shape.
Let's dwell on the basic definitions of a rhombus and try to understand what this geometric figure is.
A rhombus is an equilateral parallelogram with equal sides, but unequal angles.
Unlike a square, a rhombus is an equilateral oblique.
As always, we get a lot of definitions of a particular geometric figure, but this does not mean that every student should sit down and “cram” these definitions. The difference in definitions is how broadly they describe our geometric shape. The most important thing is understanding what the definition is about and the ability to represent the figure. If you adhere to these two rules, then you yourself can write or add a couple of definitions.
Diamond properties
2. Its second property is that all the diagonals of the rhombus intersect at right angles. At the point of intersection, the diagonals of the rhombus are halved.
3. The bisectors of the corners of a rhombus are its diagonals.
4. To find the sum of the squares of the diagonals of a rhombus, multiply the square of its side by four.
5. The opposite sides of the rhombus are equal;
6. The sum of the angles of the rhombus, which are adjacent to one of its sides, is equal to 180 degrees.
Signs of a rhombus
A parallelogram is a diamond if it meets the following conditions:
1. Firstly, all sides of him are equal;
2. Secondly, the diagonals of the rhombus intersect at right angles.
3. Third, if the diagonals of its corners are bisectors.
4. Fourth, if its two adjacent sides are equal.
5. Fifth, if at least one of the diagonals is the bisector of the parallelogram.
Theorems and their proof
Now let's take a closer look at the properties and features of the rhombus, proving the theorems:
Theorem 1
Theorem 2
It follows that:
1. The rhombus has two axes of symmetry - the diagonals AC and BD.
2. Its diagonals are mutually perpendicular.
3. And also are the bisectors of its corners.
Rhombus area
The area of a rhombus is half the product of its diagonals. But since a rhombus is, in fact, a parallelogram, its area can be found by multiplying its sides by the height.
Rhombus area formulas:
Where: a - is the side of the rhombus
D - its large diagonal is indicated
d - has the designation of the smaller diagonal
α is an acute angle
β - is an obtuse angle
The area of any geometric shape is a part of the surface that is bounded by the closed contour of this shape. And the size of the area of a rhombus is expressed by the number of square units contained in it.
How to draw a rhombus
To draw a rhombus, we will use the properties of the diagonals of the rhombus. We already know that the diagonals of our geometric figure are mutually perpendicular and are divided in half at the point of intersection. Therefore, the easiest way to start building a rhombus is to draw its diagonals.
The first way
And so, first of all, we select a point from which we lay off to the left and right segments of the same length, in up and down equal segments of a different length.
Now we just have to connect the ends of these segments, and as a result we get a rhombus.
Second way
You can also draw a rhombus without using diagonals. In this case, you only need to define the ends of the diagonals and then connect the points with segments.
The third way
And finally, the third way, drawing a rhombus can be done with a ruler. Since you and I know that the rhombus has equal sides, you first need to draw its lower part. Then you need to postpone an equal segment from it. And since the third side is parallel to the first, then connecting the ends of the first and third segments, we get a rhombus.
Repetition
You have already met such a geometric figure as a rhombus and understand that the square is its special case.
1. So let's remember the definition of what is a square? Give your own definition of a square.
2. What properties does a square have? Name them.
3. What is the difference between a rhombus and a square, if the square is its special case?
4. What figure is called a quadrangle, and does the rhombus refer to this geometric figure?
5. What types of quadrangles have you already studied? Name them.
6. What are the differences between them?
Interesting to know
Did you know that if you take a rectangle and connect the midpoints of its sides with segments, then we end up with a rhombus.
And if, on the contrary, we take a rhombus and try to connect its midpoints with segments, then we will get such a geometric shape as a rectangle.
If you take a parallelogram with equal heights, then such a parallelogram is a rhombus.
Did you know that the name of the tambourine card suit, which has a rhombic shape, appeared back in the days when the tambourine was far from a round shape, but the form of a rhombus or square.
For the first time the word "rhombus" was used in his lexicon by Herron and Pappa of Alexandria.
Homework
1. Do you think a rhombus is a parallelogram that has at least one right angle?
2. Is it true that each parallelogram is a rhombus?
3. If the diagonals of a parallelogram are 5 cm and 7 cm, can this parallelogram be a rhombus?
4. If the diagonals of a parallelogram are equal, can it be a rhombus?
5. What is a special property of a rhombus that its diagonals have, besides the fact that they are halved by the point of intersection?
6. Think about where such a geometric figure as a rhombus is used in everyday life?
