Geometry

Question Analysis:
This concept-based question checks your recognition of correct and incorrect rotation rules.

Key Concept Explanation:
Each rotation has a specific transformation rule:
90° CCW → (−y, x)
90° CW → (y, −x)
180° → (−x, −y)
Reflection over y-axis → (−x, y)

Step-by-Step Solution:
A. (−x, −y) = 180° → ✅
B. (y, −x) = 90° clockwise, not CCW → ❌
C. (−y, x) = 90° counterclockwise, not clockwise → ❌
D. (−y, x) = 270° clockwis...
