An angle inside a polygon, formed by two adjacent sides at a vertex.
Revise: Polygon AnglesAt each vertex, the angle within the polygon is an interior angle. If you continue one side beyond the vertex, the turning angle between that extension and the next side is an exterior angle.
Check whether the question asks for the sum of all interior angles or the size of one angle of a regular polygon.
Check whether a question asks for the sum of all interior angles or the size of one interior angle.
For a regular polygon, find one exterior angle using ; an interior angle is minus that exterior angle.
