Geometry

Question Analysis:
This question involves SSS congruence combined with transformations (reflection).
The main focus is on how reflections affect triangle congruence and orientation.

Key Concept Explanation:
Reflection preserves size and shape, meaning corresponding sides remain equal.
However, reflections reverse orientation (e.g., a clockwise triangle may become counterclockwise).
The SSS Congruence Postulate still applies because all three sides match.

Step-by-Step Solution:
Given PQ = XY, PR = XZ, QR = YZ, all three corresponding sides are equal.
By the SSS Congruence Postulate, the triangles must be congruent.
Since a reflection is a rigid motion, it does not change side lengths or angles.
However, reflections flip orientation, meaning the triangles are congruent but have opposite orientations.

Option Analysis:
A) Correct. SSS proves congruence, and reflections...
