To show that triangles ΔABC and ΔXYZ are congruent by the Hypotenuse-Leg (HL) Congruence Theorem, you need to confirm that you have a pair of congruent hypotenuses and a pair of congruent legs.

In this case, you've already established that:

  1. The hypotenuses AC and XZ are congruent (AC ≅ XZ).
  2. Angles B and Y are congruent (∠B ≅ ∠Y).

The HL theorem states that if the hypotenuse and one leg of a right triangle are congruent to the corresponding parts of another right triangle, then the triangles are congruent.

Since you need one leg to be congruent as well, you can choose:

AB ≅ XY or BC ≅ XZ

However, since XZ is the hypotenuse, the best option based on the choices is: AB ≅ XY

Thus, confirming AB ≅ XY will satisfy the HL congruence theorem, along with the previously established congruencies.
