PLZ HELP ME WITH GEOMETRY

Answer 1

B a counterclockwise rotation about the origin of 90°

under a counterclockwise rotation about the origin

a point ( x , y ) → (- y, x)

figure Q to figure Q'

( 4,2 ) → (- 2, 4 )

(7, 5 ) → (- 5, 7 )

(3, 7 ) → (- 7 , 3 )

(2, 4 ) → (- 4, 2 )

(5, 4 ) → (- 4, 5 )

the coordinates of the original points of the vertices of Q map to the corresponding points on the image Q'
