Rectangle A'B'C'D' is similar to rectangle ABCD. What transformations were used to get these similar shapes?

• a translation 8 units to the left, then a dilation by a scale factor of 1/2 with a center of dilation at the origin

• a reflection over the y-axis, then a dilation by a scale factor of 1/2 with a center of dilation at the origin

• a dilation by a scale factor of 1/2 with a center of dilation at the origin, then a 90 degree counterclockwise rotation about the origin

• a 90 degree counterclockwise rotation about the origin, then a dilation by a scale factor of 1/2 with a center of dilation at the origin
