How to draw a circle?

There are many ways how to draw a circle. Let's consider the most interesting of them.

Draw with squares

We need: ruler, pencil, eraser.

1. Draw a square using thin lines, which in the future can be easily erased.
2. We draw the axis of symmetry of the square - the lines that divide it in half along the sides and diagonals. The result should be four lines intersecting in the center of the square.
3. We work with diagonals. Each half-diagonal is divided into three equal parts. We mark on the half-diagonals (by means of the division) the points at the level 2/3 of the center of the first square. These points are the vertices of the new square. Draw it.
4. On the middle of each side of the first square and at each corner of the second square we mark the points (total 8). Through these points draw a circle.
5. Gently erase the auxiliary lines. It is done!

Draw with a rope

We need: a rope, an adhesive tape, a pencil.

Take the rope and measure it on the necessaryradius, we put some mark, for example, a piece of scotch tape. The end of the cord is applied to the imaginary center of the circle, the "labeled" end and the pencil is clamped between the index and middle finger and draw the circle, holding the end located in the center with the other hand.

Advice! First, draw the upper semicircle, then turn the sheet 180 degrees and repeat the work.

We draw using improvised means

We need: something round, a pencil.

If you are not friends with the eye, the aboveinstructions are unlikely to help you draw a perfectly smooth circle. In your case, you can come up with other improvised tools, which initially have a round shape. Look closely at the dishes, there is an abundance of diameters - a plate, a saucer, the base of a mug, etc.

We draw using the program

We need: a computer program, a printer.

If you did not find a round object of the desired radius, you can draw a circle using a computer program, for example, Photoshop, and then print it.

1. Open Photoshop.
2. Select the tool "Ellipse" on the toolbar, which, as a rule, is located on the left.
3. Clamp the left mouse button, and, following the prompts of the program, draw a circle of the desired radius.

You can also use the Brush tool. To do this, you need to select the shape of the brush - a circle, and in the dimensions specify the diameter of the circle that you want to draw. In this case, you only need to do one click with the left button on the canvas.

That's how many ways there are to draw a circle without a compass. On other ways read in the article How to draw a circle.
