cedric applied the rule $r_{m}circ r_{p,90^{circ}}(x,y)$ 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.

Answer

Brief Explanations:

The notation $r_m\circ R_{P,90^{\circ}}(x,y)$ means first rotate the figure $90^{\circ}$ counter - clockwise about point $P$ and then reflect it over line $m$. If he applied the reflection first, it's wrong. Also, there is no indication that the size should change during rotation and reflection, and if he changed the size instead of just rotating and reflecting, that's an error.

Answer:

He applied the reflection to the pre - image first. He changed the size of the figure instead of just applying a rotation.
