In a polygon, a line to the midpoint of one of the sides from the center is called as apothem. Find the apothem of a regular polygon or circumradius of the incircle using this free online apothem of a regular polygon calculator.

Polygon & Apothem Definition: Polygon is a closed plane figure having three or more sides. An Apothem is a line segment from center point of side of a regular polygon to the midpoint of the regular polygon. There are multiple ways to found the Apothem of a Regular Polygon. The word 'apothem' can also refer to the length of that line segment. The irregular polygons does not contain apothem or center. Hence, apothem can be calculated only for the regular polygons.
You can use this given Apothem of a regular polygon calculator to calculate the apothem of a regular polygon based on given values of the side length, circumradius and number of sides for a selected type of polygon.
