Question

If a figure located at T(-3, -1), U(1, -2), V(2, 2), W(-1, 1) and is rotated 90∘ counterclockwise rotation about the origin, which point would be the correct location of T'?
(a) (2, 1)

(b) (-1, -1)

(c) (1, -3)

(d) (-2, 2)

Answer 1

Answer:

(1, - 3 )

Step-by-step explanation:

Under a counterclockwise rotation about the origin of 90°

a point (x, y ) → (- y, x ), thus

T(- 3, - 1 ) → T'(1, - 3 )
