Find the sum of interior angles of a 53-sided polygon. It would not be practical to draw a 53-sided polygon, so the formula is more useful here. (53 – 2) × 180 = 51 × 180 = 9180.

Polygons can be regular or irregular. If the angles are all equal and all the sides are equal length it is a regular polygon. To find the sum of interior angles in a polygon divide the polygon ...
