WebSum of interior angles + Sum of the angles at O = 2n × 90° —— (1) But, the sum of the angles at O = 360° Substitute the above value in (1), we get Sum of interior angles + 360°= 2n × 90° So, the sum of the interior … WebThere are 180 (N – 2) degrees in a polygon if we add up the measures of every interior angle: Sum of Interior Angles of an N-gon = 180 (N – 2) degrees. For example, a polygon with N = 22 sides has 180 (22 – 2) = 180 (20) = 3600 degrees. That is, the sum of all interior angles in a 22-sided polygon is 3600 degrees.
