Geometry

Question Analysis:
This question asks for identification of a rigid motion using coordinate changes.
Focus is on how the y-values behave.

Key Concept Explanation:
Reflection over the x-axis changes the sign of the y-coordinates while keeping x the same.

Step-by-Step Solution:
A(1, 2) → A′(1, −2)
B(3, 4) → B′(3, −4)
C(4, 1) → C′(4, −1)

Option Analysis:
A – Incorrect: x and y would both change by fixed amounts
B – Incorrect: both x and y would be negated
C – Correc...
