Exercise 16 Page 648

The HL Congruence Theorem considers a leg and the hypotenuse of a right triangle.

Enough information is given.
Explanation: See solution.

Practice makes perfect
According to the HL Congruence Theorem, if the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and a leg of a second triangle, then the two triangles are congruent.


From the diagram we see that our right triangles have a shared hypotenuse. Therefore, by the Reflexive Property of Congruence, we know these sides are congruent.

Since the hypotenuse and a leg of △ WXZ is congruent to the hypotenuse and a leg of △ YZX, the triangles are congruent by the HL Congruence Theorem.
