Geometry

Question Analysis:
This question checks whether combining two isometries results in another isometry.

Key Concept Explanation:
The composition (combination) of two isometries is always an isometry.
Reflection and rotation are both isometries, so their combination preserves distances.

Step-by-Step Solution:
Confirm reflection and rotation are isometries.
Understand that performing one after another still preserves distances.

Option Analysis:
A: Correct—composition of isometries is an isometry.
B, C, D: Incorrect because the result i...
