## 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.

### FAQ

What is Apothem of a regular polygon?
Apothem of a regular polygon is defined as the distance between the center of the regular polygon and the midpoint of a side provided the value of side length for calculation and is represented as r=(s)/(2*tan(180/n)) or Apothem=(Side)/(2*tan(180/Number of sides)). The side is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back and The number of Sides is used to classify the polygons.
How to calculate Apothem of a regular polygon?
