Drawing circles of various diameters is far from the most necessary skill in life. However, sooner or later, the need to draw a circle without a compass and other supporting objects of a round shape takes everyone by surprise. Therefore, it is better to know in advance how to draw a circle without a compass, regardless of its diameter.
How to draw an even circle without the help of a compass
You can be a schoolboy who came to a geometry lesson, forgetting the tools for drawing, a student, an adult, forced to draw a perfectly even circle - the situations happen are different.
It will be useful for each person to know how to draw an even circle without a compass. We offer you several ways to solve this problem.
It is easy to replace the compass with another instrument located on the pencil box of each student, namely, a protractor. Put it on paper, marking the center 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 workplace, but you don’t have the right tool at hand, just use the CD. Circle it from the outside or from the inside to get a smaller shape.
In an office setting, you can also use a glass. To do this, take a glass of water, take a sip and put on a piece of paper, with a slight movement, circle the bottom. Have a drink and set it aside.
All of the above items can be found in any office, the protractor will be available to students. Using them, you can evenly draw a circle without a compass.
We draw circles of different sizes without auxiliary objects
What to do if you want to draw circles of different diameters?
It is not at all difficult to cope with this problem, having only paper and a simple pencil on hand.
Take a pencil in one hand, put the other on a piece of paper. Place the little finger of the first hand on the sheet so that it is the center of the future circle. Lock this position well. With your other hand, start turning the paper around your little finger. You will see how you get a smooth circle, as when using a compass.
A larger circle is drawn in the same way, but in this case, bend the little finger, as if all fingers were clenched 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 stylus.
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 for drawing a circle without a compass. The most important thing in these methods is to learn how to keep your right hand motionless (your left hand if you're left-handed).
How to draw a perfect circle using a ruler
If you have the usual ruler at hand, then you can use one more tip on how to draw a circle without a compass. Take the ruler and attach it to the paper, the mark `` 0 '' will be the center of the circle, so put it in the right place. Draw the second point near the digital value corresponding to the radius of the circle. Slightly shift the second edge of the ruler so that the middle remains at zero, and the third point is located slightly higher than the second.
Repeat this procedure several times. As a result, you should get a circle drawn with a dashed line. The more often the dotted line, the easier it will be to connect everything into a solid line.
This is perhaps the easiest, but at the same time the longest way to draw a circle without a compass.
