Interior angle
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).
Properties
- All the interior angles of an sided regular polygon sum to degrees.
- All the interior angles of an sided regular polygon are degrees.
- As the interior angles of an sided regular polygon get larger, the ratio of the perimeter to the apothem approaches .
