Question

Cedric applied the rule to figure WXYZ.

Figure W X Y Z is reflected across the line of reflection m to form W prime X prime Y prime Z prime. Figure W prime X prime Y prime Z prime is rotated 180 degrees about point P to form W double-prime X double-prime Y double-prime Z double-prime.
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 1

Answers:
- He applied the rotation to the pre-image first.
- He used an incorrect angle of rotation around point P.

Reason: The rule calls for reflecting WXYZ first to get W'X'Y'Z' and then rotating that image 180° about P. Cedric instead rotated the original figure (wrong order) and used the wrong rotation angle, so the final orientation is incorrect.
