To write a congruency statement for triangles, you need to specify the corresponding vertices of the triangles that are congruent. If we are looking at triangles \( \triangle WCX \) and \( \triangle WZ \), a congruency statement would generally take the form:
\[ \triangle WCX \cong \triangle WZ \]
However, since you provided "w c x z" without additional context regarding how these points are related or whether they form triangles, I could assume that:
- \( W \) corresponds to \( Z \)
- \( C \) corresponds to some point in the triangle containing \( X \) and \( Z \)
- \( X \) corresponds to another vertex of the second triangle.
If you meant two specific triangles that are congruent, please provide the full names or clarify how these points correspond to each triangle. Only with that information can I accurately create a congruency statement.
