Question

which congruence theorem can be used to prove △wxz≅△yzx?
w
x
z
y
aas
asa
sas
hl

Explanation:

In right - triangles $\triangle WXZ$ and $\triangle YZX$, we have a right - angle in each triangle ($\angle WXZ=\angle YZX = 90^{\circ}$), a common side $XZ = ZX$, and another pair of non - right angles can be equal (assume we have that information from the context or other given facts). This satisfies the AAS (Angle - Angle - Side) congruence theorem where we have two angles and a non - included side equal in the two triangles.

Answer:

A. AAS
