How to draw a circle without a compass is simple and fast

Drawing circles of different diameters -far from the most necessary skill in life. However, sooner or later the need to draw a circle without a compass and other auxiliary objects of a round shape catches everyone by surprise. Therefore, it is better to learn in advance how to draw a circle without a compass, regardless of its diameter.

How to draw a smooth circle without the help of a compass

You can be a schoolboy who came to classgeometry, forgetting tools for drawing, a student, an adult, forced to draw an ideally flat circle - situations happen different.

It will be useful to each person to know how to draw a smooth circle without a compass. We offer you several ways to solve this problem.

Replace the compasses easily with another tool,located in the pencil case in each schoolboy, namely - protractor. Put it on paper, marking the central point on the straight part, this will be the center of the future circle. Circle the inside of the semicircle, then rotate the ruler about ninety degrees and draw a third of the circle. Turn the protractor again and complete the circle.

If you are in a meeting or workingplace, but at hand was not the right tool, just use the CD. Circle it from the outside or from the inside to get a smaller figure.

In the office environment, you can also take advantage ofglass. To do this, take a glass of water, take a sip and put it on a sheet of paper, lightly stroke the bottom. Drink more and put it aside.

All of the above items can be found in any office, the protractor will be available to students. With the help of them you can draw a circle without a compass.

Draw circles of different sizes without auxiliary items

What can I do if I need to draw circles of different diameters?

It is not at all difficult to cope with this problem, having at hand only paper and a simple pencil.

Take a pencil in one hand, put the second onpaper. The little finger of the first hand is placed on the sheet so that it is the center of the future circle. Well lock this position. With the second hand, start turning the paper around the little finger. You will see how to get a smooth circle, as when using a compass.

A larger circle is drawn the same way, but in thiscase the little finger bend, as if squeezed all the fingers into a fist. With your left hand, start turning the sheet until you see the resulting circle. It is advisable to use a pencil with a soft lead.

A circle with an even larger diameter can be drawn by repeating all the above tips, but now the right hand should touch the sheet with a protruding bone on the wrist.

These are the simplest methods of how to draw a circle without a compass. The most important thing in these ways is to learn to keep the right hand still (left if you are left-handed).

How to draw an ideal circle with a ruler

If at hand you have a regular ruler, thenyou can use one more tip, how to draw a circle without a compass. Take the ruler and attach it to the paper, marking "" 0 "" will be the center of the circle, so put it in the right place. Draw a second point near the digital value corresponding to the radius of the circle. Slightly move the second edge of the ruler so that the middle remains at zero, and the third point is located just above the second.

Do this several times. As a result, you should have a circle drawn in dotted lines. The more often the dotted line, the easier it will be to put everything in a solid line.

This is perhaps the easiest, but at the same time the longest way to draw a circle without a compass.
