How many degrees are in the measure of an interior angles of a regular seven sided polygon? A formula for this question is that the total measure of the interior angles of a polygon is 180 degrees multiplied by 2 less than the number of sides. For a seven sided polyg â¦ on, this formula yields 180 X 5 = 900 degrees.
A rule of polygons is that the sum of the exterior angles always equals 360 degrees, but lets prove this for a regular octagon (8-sides). First we must figure out what each of the interior angles equal. ((n-2)*180)/n where n is the number of sides of the polygon. ((8-2)*180)/8 => (6*180)/8 => 1080/8 = 135 degrees.
