What is sum of the angles of a polygon?
Homework help has a great explanation of the answer to this question (see reference for the link).We use a formula to find the sum of the interior angles of any polygon. In this formula, the letter n stands for the number of sides, or angles, that the polygon has.sum of angles = (n - 2)180°So for a triangle (n = 3), The angles add to 180For a square (n = 4), the angles add to 360For a octagon (n = 8) the angles add to 1080
