Geometry

Question Analysis：
This question tests direct application of the 180° rotation rule about the origin.

Key Concept Explanation：
The 180° rotation rule states:
Any point (x, y) rotated 180° about the origin becomes (-x, -y)
This represents a half-turn around the origin

Step-by-Step Solution：
Original coordinates: (-6, 2)
Apply 180° rotation:
New x = -original x = -(-6) = 6
New y = -original y = -2
Final coordinates: (6, -2)

Option Analysis：
A) Correct application of (-x, -y) rule
B) Incorrect (only y-coordinate changed)
C) Incorrect (coordinate swap without rotation)
D) Incorrect (partial transformation with wrong signs and swap)
