Problem 94 of 7
Explain why reflection over the line x=-1 maps triangle UVW to triangle ZYX establishes triangle congruence.
Using a hint is okay. It just tells the trainer to give you a little more review.

reason that reflection preserves side lengths and angles.
Hidden until you reveal it.
Reflection must map one triangle to the other or its image.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. State that reflection is a rigid motion.
2. Rigid motions preserve side lengths and angle measures.
3. Therefore the preimage and image triangles are congruent.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Saying reflection fails because orientation reverses.
