Description:

Derive the interior angles formula for a polygon with n number of sides [(n-2)·180⁰].
Present the polygon exterior angles theorem (the sum of the measures of the exterior angles of a convex polygon, one angle at each vertex, is 360⁰).
Demonstrate how to solve for the measure of an interior or exterior angle of a polygon.
Provide examples that allow practice solving for unknown variables and angle measures.

This packet should help a learner seeking to understand how to determine the measures of interior and exterior angles of polygons.
