Sum of exterior angles formula
Web6 Dec 2024 · According to this theorem, in a convex polygon, the sum of all the exterior angles is equal to 360°. This can be proved in the following way; We know that sum of … WebThe sum of angles is obtained using the formula for the sum of polygons angles: (n-2)\times 180 (n − 2) × 180 ° where, n is the number of sides of the polygon. For a hexagon, we use n = 6 n = 6. Therefore, we have: (n-2)\times 180 (n − 2)× 180 ° = (6-2)\times 180 = (6 − 2)× 180 ° = (4)\times 180 = (4)× 180 ° =720 = 720 °
