The formula for finding the total measure of all interior angles in a polygon is (âânââ â 2) x 180, where âânââ is the number of sides, as well as the number of angles, the polygon has. Some common polygon total angle measures are as follows: The angles in a triangle (a 3-sided polygon) total 180 degrees.
