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. Therefore, the values of x and y are ... WebClick on "Calculate". Unlike the manual method, you do not need to enter the first vertex again at the end, and you can go in either direction around the polygon. The internal programming of the calculator takes care of it all for you. There are other, often easier ways to calculate the area of triangles and regular polygons. WebTwo ears theorem.
