## How to define a regular polygon?

A regular polygon has sides of equal length and equal angles between each side. A regular n-sided polygon has rotational symmetry of order n and it is also known as a cyclic polygon. All the vertices of a regular polygon lie on the circumscribed circle.

## How to Calculate Apothem of a regular polygon when the circumradius is given?

Apothem of a regular polygon when the circumradius is given calculator uses Apothem=Radius Of Circumscribed Circle*cos(180/Number of sides) to calculate the Apothem, Apothem of a regular polygon when the circumradius is given can be defined as the distance between the center of the regular polygon and the midpoint of a side provided the value of circumradius for calculation. Apothem and is denoted by r symbol.
