In geometry, an interior angle (or internal angle) is an angle formed by two sides of a simple polygon that share an endpoint, namely, the angle on the inner side of the polygon. A simple polygon has exactly one internal angle per vertex.

Previous Level: 8.2 Angle 54° Trisection.
When two parallel lines are intersected by a transversal, two groups of four angles of equal measurement are created. The four smaller angles have equal measurements just as the four larger angles.

The formula for all the interior angles is: [()] = [()] where n is the number of sides. In a regular polygon, one internal angle is equal to [()] = [()] .
By internal angles. Triangles can also be classified according to their internal angles, measured here in degrees . A right triangle (or right-angled triangle, formerly called a rectangled triangle) has one of its internal angles equal to 90° (a right angle ).
For a simple polygon (non-self-intersecting), regardless of whether it is convex or non-convex, this angle is called an internal angle (or interior angle) if a point within the angle is in the interior of the polygon. A polygon has exactly one internal angle per vertex.
