- AAB = PQ
- B∠C = ∠R
- CAC = PR
- DBC = QR
Step-by-Step Solution
∠C = ∠R follows anyway from the angle sum, so it adds no side information — that is just AAA. Any one pair of corresponding sides would give ASA or AAS.
Answer: B) ∠C = ∠R
In △ABC and △PQR, ∠A = ∠P and ∠B = ∠Q. Which extra condition does NOT prove the triangles congruent?
