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:
