Geometry

Question Analysis:
You are asked to identify the correct rotation that maps one triangle onto another, using their coordinates.

Key Concept Explanation:
270° counterclockwise is equivalent to 90° clockwise, and its rule is:
(x, y) → (y, −x)
180° rotation uses the rule: (x, y) → (−x, −y)

Step-by-Step Solution:
(3, −2) → (−3, 2) ✅
(5, −2) → (−5, 2) ✅
(5, −5) → (−5, 5) ✅
180° rotation uses the rule: (x, y) → (−x, −y)
Correct Answer is A. 180°

Option Analysis:
A. ✅ 180° → all coordinates match perfectly
B. 90° CW → gives wrong coordinates
C. 270° CCW → same as 90° CW → also wrong
D. Reflection over x-axis → wo...
