Question

Which rule represents R0, 180°? (x, y) → (–y, x) (x, y) → (–x, –y) (x, y) → (y, –x) (x, y) → (y, x)

Answer 1

Answer:

(x, y) → (–x, –y)

Step-by-step explanation:

The rule for 180° rotation about the origin is

$(x,y)\to (-x,-y)$

The coordinates of the image are obtained by negating both the x and y coordinates of the preimage.

Whether the rotation is clockwise or counterclockwise, the rule remains the same.

The correct option is (x, y) → (–x, –y)
