The Solution:
Given the figure below:
We are to identify the option that is not sufficient to prove that:
[tex]\Delta WXZ\cong\Delta WYX[/tex]
Clearly, option H is not sufficient.
[tex]\begin{gathered} \angle WXZ\cong\angle Y\text{ is not sufficient since} \\ \angle WXY\ne\angle\text{WZX}=90^o \end{gathered}[/tex]
Therefore, the correct answer is [option H]
