How To Draw A Perfect Circle?

Everyday we come across different shapes in ourΒ day to day life. Many of us are already aware of a couple of them such as Circles, Squares, Triangle, parallelogram, hexagons, and so on. The characteristic property of different geometrical figures are length, breadth, , diameter, etc. which make them unique from one another. Hence, to construct any of the geometrical figure, their distinctive properties must be known to us. Practical geometry is the most pragmatic branch of geometry that deals with the construction of different geometrical figures using tools such as rulers, compasses and protractors. In this article, we will discuss how to draw a circle of a given radius.

The Circle

Before we move over to the procedure to learn how to draw a circle, it is required for you to keep some of its properties in mind.


Radius and Diameter of a Circle

  • The diameter is any straight line segment that passes through the center of the circle and joins two opposite points lying on the boundary of the circle.
  • Β The Radius of circle is a straight line segment that joins the center of the circle to any point on its boundary.
  • Every point on the boundary of a circle is equidistant from its center.
  • The length of any radius of a circle is half of its diameter.

How to Draw a Circle of a Given Radius?

To draw a circle whose radius is given, we require a ruler and compasses. Given that the radius is 5 cm, the steps to be followed are:

  • Step 1: Place the pointer of the compass at the initial point of the ruler (0 cm) and extend the other end of the pencil measuring 5 cm from the initial point (i.e. 5 cm)
  • Step 2: Mark a point O on a piece of paper. This point is supposed to be the center of the circle that you are about to construct.
  • Step 3: Place the pointer of the compass at point O.
  • Step 4: Turn the compass slowly through 360 degrees to draw a circle.

Construction of Circle


Make sure that you hold the point of the compass stiffly on the paper. You are also required to move the compass through the 360 degrees in one go for accuracy and neatness.
