Geometry

Question Analysis:
This question tests your ability to distinguish between rigid and non-rigid transformations.
The main focus is on identifying when congruence is preserved.

Key Concept Explanation:
Rigid motions (reflection, rotation, translation) preserve size and shape. Dilation does not — it alters size.

Step-by-Step Solution:
Only choice C includes dilation, which changes the size of the figure, breaking congruence.

Option Analysis:
A – Only rigid motions → congruent.
B – Same → congruent.
C – Includes dilation → n...
