PLEASE HELP URGENT Match the reasons with the statements in the proof to prove AB || DC, given that AD is parallel to BC and AD = CB. Given: AD || BC AD = CB Prove: AB || DC 1. AD || BC, AD = CB SAS (Side-Angle-Side) 2. AC = AC CPCTE (Corresponding Parts of Congruent Triangles are Equal) 3. 2 = 3 Reflexive Property of Equality 4. ACD = CAB Given 5. 1 = 4 If Alternate Interior Angles are Congruent, then Lines are Parallel. 6. AB || DC If Lines are Parallel, then Alternate Interior Angles are Equal.
