Answer:

  1. R'(-2, 2)
  2. F'(2, 2)
  3. G'(-2, -2)

Explanation:

It can be useful to keep a list of the 90° rotation transformations.

(x, y) ⇒ (-y, x) . . . . . . 90° CCW, 270° CW

(x, y) ⇒ (-x, -y) . . . . . . 180°

(x, y) ⇒ (y, -x) . . . . . . . 270° CCW, 90° CW

__

1) (x, y) ⇒ (-x, -y) . . . . 180°

R(2, -2) ⇒ R'(-2, 2)

__

2) (x, y) ⇒ (-y, x) . . . . 90°

F(2, -2) ⇒ F'( 2, 2)

__

3) (x, y) ⇒ (y, -x) . . . . 270°

G(2, -2) ⇒ G'(-2, -2)
