Geometry

Question Analysis:
This question focuses on identifying a transformation based on coordinate changes of all points.

Key Concept Explanation:
Reflection over the x-axis: (x, y) → (x, −y)
Check whether y-values are negated while x stays the same.

Step-by-Step Solution:
(1, 2) → (1, −2)
(3, 2) → (3, −2)
(2, 5) → (2, −5)
→ All y-values flipped; x unchanged
✅ So reflection over x-axis

Option Analysis:
A: translation would...
