Geometry

Question Analysis:
Examines understanding of invariant properties in geometric transformations.

Key Concept Explanation:
Isometries preserve:
Distance
Angle measures
Area
But may change orientation (e.g., reflections)

Step-by-Step Solution:
Option C:
Reflections reverse orientation
Other options:
A/B/D: Always preserved

Common Mistakes:
Assuming all properties are pre...
