Geometry

Question Analysis:
This question tests knowledge of how different transformations affect the properties of a parallelogram.

Key Concept Explanation:
Rigid motions (translations, rotations, reflections) preserve distances and bisect diagonals.
Dilation changes size, which affects diagonal bisection.

Step-by-Step Solution:
A rigid motion would keep the parallelogram’s diagonals bisected. 
Dilation scales all distances, which may result in diagonals no longer bisecting each other at the same point. 

Option Analysis:
A) Rotation (Incorrect) – Rotations preserve diagonal bisection.
B) Reflection (Incorrec...
