Answer:
- R'(-2, 2)
- F'(2, 2)
- G'(-2, -2)
Step-by-step 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)
