It looks like you need help completing the proof to show that $\angle WXZ \cong \angle VYZ$. Let’s break this down step-by-step based on the given diagram.

Proof of $\angle WXZ \cong \angle VYZ$:

This type of proof typically involves parallel lines and corresponding angles. From the diagram, we can see that two lines are intersected by a transversal.

1. Statement: $\angle XWZ \cong \angle YVZ$

   • Reason: Given.

2. Statement: $WX \parallel VY$

   • Reason: This is likely a given property in the diagram, suggesting that the lines $WX$ and $VY$ are parallel.

3. Statement: $\angle YVZ \cong \angle WXZ$

   • Reason: Corresponding Angles Postulate. Since $WX \parallel VY$, corresponding angles formed by the transversal $XZ$ and $YZ$ are congruent.

4. Statement: $\angle XWZ \cong \angle VYZ$

   • Reason: Vertical Angles Theorem. In the diagram, $\angle XWZ$ and $\angle VYZ$ are vertical angles and vertical angles are always congruent.

5. Statement: $\angle YVZ \cong \angle VYZ$

   • Reason: Transitive Property. From earlier statements, we can now conclude that these angles are congruent by the transitive property.

6. Statement: $\angle WXZ \cong \angle VYZ$

   • Reason: Definition of congruent angles. We've now proven that these two angles are congruent, completing the proof.
