coordinate of the vertices after a rotation 270 grades counterclockwise around the origin d (2 2) F (3 4)E(9 2)

If the point (x, y) is rotated 270 degrees counterclockwise around the origin
Then its image is (y, -x)
We change the sign of the x-coordinate and switch the two coordinates
Since point D = (2, 2), then
Its image is D' = (2, -2)
Since point E = (9, 2), then
Its image E' = (2, -9)
Since point F = (3, 4), then
Its image F' = (4, -3)
