So first six sided polygon is called hexagon. and the sum of all interior angles in a hexagon is 720° so if you divide that by six. since it has six interior angles, the angle of each interior angle will be 120° as of exterior angle. *note: the sum of the interior angle and its corresponding angle is always 180° so if you subtract 120° from 180° you have 60° so all exterior angles are 60°
