Exterior Angles Of A Polygon Gcse Maths Revision Guide We know the sum of exterior angles for a polygon is 360°. 3 solve the problem using the information you have already gathered with use of the formulae interior angle exterior angle =180 ∘ = 180∘ and sum of interior angles =(n − 2) × 180 ∘ = (n − 2) × 180∘ if required. the size of each exterior angle is 60º. The sum of exterior angles of a polygon is 360°. the formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides. learn about and revise angles.
