Use this diagram of a regular pentagon to explain how to determine the formula for finding the vertex angle in a regular polygon.
Divide the pentagon into three triangles. The sum of the degree measures
of the three triangles is the same as the sum of the degree measures of the
vertex angles of the regular pentagon. Since each vertex angle in the regular
