Quadrilateral wxyz, with a vertex y at (-3, 0), is rotated counterclockwise 270° about the origin. which of the following rotations is equivalent to 270° counterclockwise rotation about the origin? clockwise 90° counterclockwise 90° counterclockwise 360° clockwise 270°

The correct answer is clockwise 90 degrees. There are 360 degrees in a compete rotation, so if you turn it 270 degrees clockwise (that would leave you only 90 degrees to get back to where you started. If you go in the opposite direction, it will only take 90 degrees to get to that point.
