Question

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

Answer 1

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)
