If the point (x, y) rotated 90 degrees counter-clockwise, then its image is (-y, x)

If the point (x, y) rotated 180 degrees clockwise or counter-clockwise, then its image is (-x, -y)

It the point (x, ) rotated 90 degrees clockwise or 270 degrees counterclockwise, then its image is (y, -x)

Since point D (2, 2) is roteated 90 degrees counterclockwice, then

D' = (-2, 2)

Since point C (1, 3) is rotated 90 degrees clockwise, then

C'' = (3, -1)

Since point A (-4, 2) is rotated 180 degrees clockwise, then

A''' = 4, -2)

Since the point B (-2, 4) is rotated 270 degrees counterclockwise, then

B'''' = (4, 2)

The coordinates of point D' if polygon ABCD is rotated 90 counterclockwise is (-2, 2)

The coordinates of point C'' if polygon ABCD is rotated 90 degrees clockwise is (3, -1)

The coordinates of point A''' if polygon ABCD is rotated 180 degrees clockwise is (4, -2)

The coordinates of point B'''' if polygon ABCD is rotated 270 degrees counterclockwise is (4, 2)
