Geometry

Question Analysis:
This question tests the understanding of what is preserved in an isometry.

Key Concept Explanation:
An isometry maintains all distances and angles, meaning:
Area, angles, side lengths, and perimeter remain unchanged.

Step-by-Step Solution:
Check properties preserved by isometries:
Angles remain unchanged ✅
Side lengths remain unchanged ✅
Perimeter and area remain unchanged ✅

Option Analysis:
A) Area and angles (Partially correct) – Side lengths are also preserved.
B) Side lengths and perimeter (Partially correct) – Angles are also preserved.<...
