Question

If the following figure is rotated 90° clockwise about the origin, what is the new location?

A. E’ (6, 2), F’ (-4, 7), G’ (7, -2) H’ (1, -5)

B. E’ (-6, -2), F’ (4, -7), G’ (-7, 2), H’ (-1, 5)

C. E’ (6, -2), F’ (-4, -7), G’ (-7, 2), H’ (1, 5)

D. E’ (-6, 2), F’ (4, 7), G’ (-7, -2), H’ (-1, -5)

Answer 1

Answer:

C

Step-by-step explanation:

Under a clockwise rotation about the origin of 90°

a point (x, y ) → (y, - x ), thus

E(2, 6 ) → E'(6, - 2 )

F(7, - 4 ) → F'(- 4, - 7 )

G(- 2, - 7 ) → G'(- 7, 2 )

H(- 5, 1 ) → H'(1, 5 )

Answer 2

C. E’ (6, -2),F’ (-4, -7), G’ (-7, 2), H’ (1, 5)
