Geometry

Question Analysis:
This question evaluates your understanding of coordinate-based rotations, specifically how point positions shift after a 90° clockwise turn.

Key Concept Explanation:
The rule for a 90° clockwise rotation about the origin is:
(x, y) → (y, −x)

Step-by-Step Solution:
Apply the rule to each point:
(−3, 1) → (1, 3) ✅
(−3, 4) → (4, 3) ✅
(−6, 4) → (4, 6) ✅
Every rotated point matches the corresponding red triangle vertex.

Option Analysis:
A. ✅ 90° clockwise → rule fits perfectly
B. 180° → (x, y) → (−x, −y) → gives (3, −1), incorrect
C. 90° counterclockwise → (x, y) → (−y, x) → gives (−1, −3), incorrect
D. 270° CW = 90° CCW...
