WebExterior angles are angles between a polygon and the extended line from the vertex of the polygon. Sum of exterior angles of a polygon = 360º. Interior and exterior angles … WebExterior angles in a polygon are found by using the formula 360°/Number of sides of the polygon. If there are 9 sides in the polygon, then each exterior angle in the polygon is equal to 360°/9, which is 40°. The same formula is applicable to a regular polygon and an … Exterior Angle Theorem. The exterior angle theorem states that when a triangle's …
WebTo calculate the exterior angles of an irregular polygon we use similar steps and formulas as for regular polygons. The sum of the exterior angles of a polygon is equal to 360°. Therefore, the formula is, Sum of exterior angles = 180n – 180 (n-2) = 180n – 180n + 360. Hence, the sum of exterior angles of a pentagon equals 360°. WebExterior angle of a Pentagon: n = 5. Measure of each exterior angle = 360°/n = 360°/5 = 72° NOTE: The interior angle and exterior angle formulas only work for regular …
