Solution.
Given that AB≅ ZX, ∠A ≅ ∠Z, AC≅ XY
Considering the two triangles above. Two sides and one angle of the triangles are equal to each other , but the equal angle is not the inluded angle to both triangles, thus, we cannot conclude that the two triangles are congruent by SAS. Also, since the two triangles do not not both have equal sides, we can not conclude that they are congruent by SSS either.
Thus, the correct option is Not enough information
