Answer:
B. XY = AB
Explanation:
Two triangles are congruent by ASA if they have two congruent angles and the side between them is also congruent.
In this case, ∠X is congruent to ∠A and ∠Y is congruent to ∠B. Then, the sides between them are XY for the first triangle and AB for the second. Therefore, the sides that need to be congruent are XY and AB, so the answer is
B. XY = AB
