WebLearn about and revise the different angle properties of circles described by different circle theorems with GCSE Bitesize AQA Maths. 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 ...
