Ben transformed a figure from quadrant IV to quadrant I. The pre-image and image are congruent figures, but the orientation of the figure changed. Which could be the transformation Ben used? (two of the below answers change the orientation of the figure, but only one can get you from quadrant IV to quadrant I)

• A dilation by a scale factor of 2

• A translation up

• A reflection over the y-axis.
