Once you have identified all of the information you can from the given information, you can figure out which theorem will allow you to prove the triangles are congruent. exercise boxes, organized by sections.Taking the Burden out of ProofsYesTheorem 8.3: If two angles are complementary to the same angle, then these two angles are congruent. Given: AM = CP, CM 3GP, C Is The Midpoint Of AG Prove: AACM ACGP M Reasons 1. • Use information from the diagram. Given: GA || TE Given: Prove: AB ≅ CB , BD is a median of AC ΔABD ≅ ΔCBD Statement Reason C is the midpoint of DB and AE Given BC≅CD The midpoint C creates two equal parts AC≅CE The midpoint C creates two equal parts ∠ACB≅∠DCE Vertical Angles are congruent ∴ΔABC≅ΔEDC by the SAS postulate.
