WebDec 6, 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 interior angles of a polygon is given by 180° × (n-2) where n is the number of sides of the polygon. So, the measure of each interior angle of the polygon will be 180° × (n-2) / n. WebPolygon. A polygon is a two-dimensional geometric figure that has a finite number of sides.

WebExterior Angle Theorem Examples. Example 1: Find the values of x and y by using the exterior angle theorem of a triangle. Solution: ∠x is the exterior angle. ∠x + 92 = 180º (linear pair of angles) ∠x = 180 - 92 = 88º. Applying the exterior angle theorem, we get, ∠y + 41 = 88. ∠y = 88 - 41 = 47º.
