Geometry

Question Analysis:
This question assesses the ability to apply reflection rules to multiple points of a shape.

Key Concept Explanation:
Reflecting a shape over the x-axis requires reflecting each vertex individually using the same rule:
x-coordinates stay the same,
y-coordinates change sign.

Step-by-Step Solution:
Original vertices:
A(1, 2) → A'(1, -2)
B(4, 6) → B'(4, -6)
C(2, 7) → C'(2, -7)

Option Analysis:
A) Correct (all y-coordinates flipped).
B) Incorrect (x-coordinates wrongly negated).
C) Incorrect (no change—original positions).
D) Incorrect (both x and y wrongly negat...
