Interior Angles And Exterior Angles Of Polygons. Measure of a Single Exterior Angle Formula to find 1 angle of a regular convex polygon of n. The same is called a polygon exterior angle sum theorem.
In the figure angles 1 2 3 4 and 5 are the exterior angles of the polygon. 181 exterior angle p. When we add up the Interior Angle and Exterior Angle we get a straight line 180.
The sum of the measures of the exterior angles of a polygon one at each vertex is 360.
The angles are formed by one side of the polygon and extension of the other side. The same is called a polygon exterior angle sum theorem. It has four right angles 90. You can find the interior angle of a regular polygon by dividing the sum of the angles by the number of angles.
