The interior angle is the angle between two line segments, having two endpoints connected via a path, facing the path connecting them.

All of the interior angles of a regular polygon are congruent (in other words, regular polygons are equiangular).

All the interior angles of an $n$ sided regular polygon sum to $(n-2)180$ degrees.
All the interior angles of an $n$ sided regular polygon are $180(1-{2\over n})$ degrees.
As the interior angles of an $n$ sided regular polygon get larger, the ratio of the perimeter to the apothem approaches $2\pi$ .
