exterior angle
Angle beyond polygon
An exterior angle is formed when one side of a polygon is extended beyond a vertex, creating an angle between that extension and the adjacent side.
In a triangle, each exterior angle equals the sum of the two non-adjacent interior angles.
The exterior angles of any convex polygon sum to 360 degrees.
