Sum Of Interior And Exterior Angles Of Polygons Youtube Learn how to find interior and exterior angles in polygons as well as in regular polygons in this video math tutorial by mario's math tutoring. we discuss 4. Since an exterior angle is formed by extending a side, the sum of the interior and the exterior angle on the same vertex of any polygon is 180°. the formula to determine the sum of exterior angles is derived below: now, for any polygon with n sides, sum of exterior angles sum of interior angles = n x 180° thus,. The interior angles of a polygon are angles inside the shape. the exterior angles of a polygon are angles outside of the shape formed between any side of the polygon and a line extended from the side next to it. if we imagine the polygon as a house, the in terior angles live in side of the house, while the ex terior angles live in ex ile. For a regular polygon, each exterior angle is the same, so each interior angle of an n sided polygon is: sum of interior angles = (n 2) x 180 n. the diagram shows the sum of the interior angle of a 5 sided polygon, or pentagon, which is 3 times 180°, or 540°. each interior angle of a regular pentagon is 3 times 180° divided by 5, or 108°.
