Cedric applied the rule to figure WXYZ. What mistakes did he make? Select two options. He applied the reflection to the pre-image first. He applied the rotation to the pre-image first. He changed the size of the figure instead of just applying a rotation. He used point P as the center of rotation. He used an incorrect angle of rotation around point P.
