WebTo find: The measure of each interior angle of a regular polygon of 23 sides. The number of sides of the given polygon is n = 23. By interior angle formula, The sum of interior angles = 180(n-2)º= 180 (23-2)º = 180 (21) º = 3780º. The measure of each interior angle is obtained by dividing the above sum by 23. Each interior angle = 3780 / 23 ... WebJun 15, 2024 · Just divide the sum of the angles by the number of sides. Regular Polygon Interior Angle Formula: For any equiangular n−gon, the measure of each angle is (n − 2) × 180 ∘ n. Figure 5.27.3. In the picture below, if all eight angles are congruent then each angle is (8 − 2) × 180 ∘ 8 = 6 × 180 ∘ 8 = 1080 ∘ 8 = 135 ∘. Figure 5.27.4.

WebApr 6, 2024 · In the case of regular polygons, the measure of each interior angle is congruent to the other. A Theorem about Interior Angles. Here will prove the polygon … WebJan 2, 2016 · Explanation: The sum of the interior angles in a regular polygon with n sides is found through the formula. 180˚(n −2) Here, n = 20, so the sum of the interior angles is. 180˚(20− 2) = 180˚(18) = 3240˚. To find just one angle, divide 3240˚ by 20 since all 20 angles are congruent. 3240˚ 20 = 162˚. Answer link. WebWe know that the sum of all interior angles of a polygon of n sides is 180(n-2)° degrees. Hence, the sum of the interior angles of the pentagon is: 180 × (5-2)° =180 × (3)° = 540° Since the given pentagon is regular, … open university maths help
