Tasha is creating animated objects for a website. She uses rotations in the coordinate plane to describe how the objects move. The graph shows Tasha’s sketch of the image of parallelogram ABCD after a 270° rotation about the origin. Did Tasha graph A’B’C’D’ correctly? Explain.
because a 270° rotation about the origin transforms the point (x,y) to the point
In the sketch, the coordinates of corresponding points in ABCD and A’B’C’D’
