Geometry

Question Analysis:
This question tests your understanding of how one point changes under various transformations.

Key Concept Explanation:
Use the rotation rules to test each transformation:
90° CCW: (x, y) → (−y, x)
180°: (x, y) → (−x, −y)
90° CW: (x, y) → (y, −x) 

Step-by-Step Solution:
Check each one using rotation rules.
90° CCW: (x, y) → (−y, x) → (−4, 1) ✅
180°: (x, y) → (−x, −y) → (−1, −4) ✅
90° CW: (x, y) → (y, −x) → (4, −1) ✅
