Answer:
A: Might not be congruent.
Explanation:
It is given <U≅<X, <V ≅<Y ,<W≅<Z.
The three angles of both the triangles are congruent.So the triangles are similar by AAA similarity postulate.AAA is not a congruence postulate .All similar triangles need not be congruent.
Hence it is not necessary Δ UVW ≅Δ XYZ,as AAA is not a congruence postulate.
Among all the given options option A : Might not be congruent is the right option.
