interior angle The sum of the exterior angles of a polygon is always 360°. In a regular polygon, to find an exterior angle, you can divide 360° by the number of sides (360 n). An interior angle and its corresponding exterior angle add up to 180°. The formula for the sum of the interior angles in a polygon is: (n – 2) × 180° (where n is ...
