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.

Calculating the size of each exterior angle of regular polygons The formula for calculating the size of an exterior angle of a regular polygon is: \({exterior~angle~of~a~regular~polygon}~=~{ ...

A pentagon contains 3 triangles. The sum of the interior angles is: All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is ...

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.
