so the formula is more useful here. (53 – 2) × 180 = 51 × 180 = 9180. The interior angles of a 53-sided polygon sum to 9180°. A regular polygon is a polygon with all sides and angles equal.
The formula for calculating the sum of interior angles is: \(({n}~-~{2})~\times~180^\circ\) (where \({n}\) is the number of sides) All the interior angles in a regular polygon are equal.
