If WX ≅ WZ, it means that the two sides WX and WZ are congruent.
If both triangles share the common side WX and also have the same angle at P, then it is Side-Angle-Side (SAS) congruence.
Therefore, with WX ≅ WZ and ∠PXW ≅ ∠PZW, we can conclude that the triangles ΔPXW and ΔPZW are congruent ΔPXW ≅ ΔPZW.
