Congruent Polygons
242 Chapter 5 Congruent Triangles Using the Third Angles Theorem Find m∠BDC. SOLUTION ∠A ≅ ∠B and ∠ADC ≅ ∠BCD, so by the Third Angles Theorem, ∠ACD ≅ ∠BDC. By the Triangle Sum Theorem (Theorem 5.1), m∠ACD = 180° − 45° − 30° = 105°. So, m∠BDC = m∠ACD = 105° by the defi nition of congruent angles. Proving That Triangles Are Congruent
