Formula of exterior angles of a polygon

WebWe can see that all the exterior angles of a polygon have a total sum of 360°. Therefore, we can calculate the measure of one of the exterior angles of a regular polygon by dividing 360° by the number of sides of the regular polygon. For example, for a pentagon, we have: 360°÷5 = 72° Each exterior angle of a regular pentagon measures 72°. WebFeb 24, 2012 · Because the polygon is regular, the interior angles are equal. It also means the exterior angles are equal. 360 ∘ 7 ≈ 51.43 ∘. Example 5. What is the sum of the exterior angles in a regular 15-gon? The sum of the exterior angles in any convex polygon, including a regular 15-gon, is 360 ∘. Review

WebSo five corners, which means a pentagon. this means there are 5 exterior angles. since they all have to add to 360 you can divide 360/5 = 72. You can also check by adding one interior angle plus 72 and checking if you get … WebAn interior angle is an angle that lies inside a polygon. The number of interior angles in a polygon is equal to its number of sides. For example, a polygon with three sides, a triangle, will have three interior angles. Each type of polygon has a different sum of interior angles. An angle is measured in degrees or radians.

WebThe sum of interior angles of different polygons is different. The sum of all interior angles of a polygon with ‘n’ number of sides can be calculated by the formula, [ (n-2) x 180]°.
