Question

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

Answer 1

(x, y) → (–x, –y) option B

Explanation:

Answer 2

(x, y) → (–x, –y)

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)
