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.
1. Count the number of sides your polygon has. The method for calculating the sum of interior angles is based on how many sides the polygon has. Remember that a polygon must have at least 3 sides (a triangle), and each side must be a straight line.
