Apothem Definition

In geometry, apothem is defined as the distance between the midpoint or central point to any regular side of polygons. In other words, a straight line from a midpoint of the regular polygon perpendicular to any of its sides is known as apothem.

Equivalently, "apothem" is the line stretched from the polygon’s center to one of its perpendicular sides. However, the only polygons with apothems are regular polygons.

To see one of the example of the apothem, check out the diagram listed below:
