Geometry

Question Analysis:
This tests whether you understand that multiple transformations can produce the same result as a single rotation.
The main focus is on recognizing angle accumulation and reflection equivalence.

Key Concept Explanation:
90° + 90° = 180° (same direction → same result)
Rotating 180° CCW = Rotating 180° CW
Reflecting over both x and y axes also gives (–x, –y), which matches 180° rotation

Step-by-Step Solution:
A. ✅ 90° + 90° = 180°
B. ✅ Same angle, correct
C. ❌ 90° × 4 = 360°, returns to original
D. ✅ Reflecting across x-axis: (x, y) → (x, –y), then y-axis → (–x, –y) = 180° rotat...
