If two angles in one triangle are congruent to two angles in another triangle, then the third pair of angles must also congruent. This is called the Third Angle Theorem. If ∠A ≅ ∠D and ∠B ≅ ∠E, then ∠C ≅ ∠F.
WebJul 21, 2024 · The vertical angles theorem tells us that the angle opposite of the 60° angle must also be 60°. The sum of this pair of vertical angles is 120°. 360 – 120 = 240. 240/2 = 120. Hence, angles 60°, 60°, 120°, and 120° of the intersection. When two lines cross it makes four angles (making two sets of vertical angles). WebThe vertical angles are formed. We have to prove that: Since the measure of angles 1 and 2 form a linear pair of angles. So, Similarly, the measure of angle 2 and 3 also form a …
