Question Analysis:
This question asks you to determine the correct rotation that maps one triangle to another using vertex coordinates.

Key Concept Explanation:
A 180° rotation about the origin follows the rule:
(x, y) → (−x, −y)
90° CW rotation rule: (x, y) → (y, -x)
90° CCW rotation rule: (x, y) → (-y, x)
reflection across the y-axis: (x, y) → (−x, y)

Step-by-Step Solution:
(2, −5) → (−2, −5) ✅
(5, −5) → (−5, −5) ✅
(5, −2) → (−5, −2) ✅
All red triangle points match this reflection, not rotation.
Corrected ✅ Answer: D. No rotation — this is a reflect...
