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. WebOctagons have 8 sides so again, we need to adjust the formula accordingly: sum of internal angles = (8 - 2) x 180°. 1080° = 6 x 180°. In a regular octagon, one angle would be worth: 1080° ÷ 8 ...
