Is triangle UVW congruent to triangle XYZ? If so , name the postulate that applies

The postulate that applies depends on which corresponding parts of the two triangles are congruent. For example, if three corresponding sides of one triangle are congruent to three corresponding sides of another triangle, then the two triangles are congruent to each other by the Side-Side-Side (SSS) Postulate. Without knowing which corresponding parts of the two triangles are congruent, however, it is not possible to answer this question.
