   : View Source, ShowAbout bperkhou: I am a student at Stanford University. In this video lesson I discuss the sum of angles of polygons. There is a formula for this sum of angles that depends only on the number of sides of the polygon: if it has n sides, the sum of the angles is 180(n-2). We use this fact to find missing angles in several examples, and to find the interior angles of regular polygons, where each angle is equal. For more details, see the lesson.
