Geometry

Question Analysis：
This question is centered around the concept of congruent triangles.
The main focus is to understand the correct correspondence of sides in congruent triangles.
Given that △XYZ≅△PQR, we need to determine which set of equal - side relationships is correct.

Key Concept Explanation：
When two triangles are congruent, the order of the vertices in the congruence statement △XYZ≅△PQR indicates the correspondence of their parts.

Step - by - Step Solution：
Side XY is between vertices X and Y in △XYZ. In △PQR, the corresponding side is between the corresponding vertices P and Q, so XY = PQ.
Side YZ is between vertices Y and Z in △XYZ. In △PQR, the corresponding side is between the corresponding vertices Q and R, so YZ = QR.
Side XZ is between vertices X and Z in △XYZ. In △PQR, the corresponding side is between the corresponding vertices P and R, so XZ = PR.

Option Analysis：
Option A: YZ = PR and XZ = QR are incorrect. The correct correspondence is YZ = QR and XZ = PR. So, this option is wrong.
Option B: XY = PR, YZ = PQ are incorrect. The correct equalities are XY = PQ and YZ = QR. So, this option is wrong.
Option C: XY = QR, YZ = PR, XZ = PQ are all incorrect. The correct equalities are XY = PQ, YZ = QR, XZ = PR. So, this optio...
