Construction of a circle:

To construct a circle, we should make a note of the radius.

Radius is the only component required to construct a circle.

Now, let us learn to construct a circle step-by-step.

Construct a circle with $3cm$ as radius.

Step $1$ : Mark the fixed point as '

$O$ '.

Step $2$ : Draw a line segment of

$3cm$ from '

$O$ '. Mark the other end of the line segment as '

$A$ '.

Step $3$ : With '

$O$ ' as centre, rotate the compass firmly from '

$A$ ' until the circle is achieved.

Practical construction is as follows:
