Step-by-Step Solution
∠BAC = ∠DCA (alternate angles, as l ∥ m), AC is common, and ∠BCA = ∠DAC (alternate angles, as p ∥ q). The common side lies between the two angle pairs: ASA.
Answer: A) ASA
Lines l ∥ m are cut by parallel lines p ∥ q, forming parallelogram ABCD with diagonal AC. By which rule is △ABC ≅ △CDA?
