WebTheorem 39: If a convex polygon has n sides, then its interior angle sum is given by the following equation: S = ( n −2) × 180°. The polygon in Figure 1 has seven sides, so using Theorem 39 gives: An exterior angle of a polygon is formed by extending only one of its sides. The nonstraight angle adjacent to an interior angle is the exterior ... WebSum of Angles of a Polygon. 1. Sum of the interior angles of a polygon: Sum of the interior angles of a polygon with n sides = (n – 2) × 180° For example: Consider the following polygon with 6 sides. Here, ∠a + ∠b + ∠c + ∠d + ∠e + ∠f = (6 – 2) × 180° = 720° (n = 6 as given polygon has 6 sides) 2. Sum of the exterior angles ...
