Problem 95 of 7
Explain why a reflection followed by a translation preserves congruence.
Using a hint is okay. It just tells the trainer to give you a little more review.

state preservation of distance and angle measure.
Hidden until you reveal it.
Rigid motion must be translation, rotation, reflection, or a sequence of these.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Name the rigid motion.
2. State that rigid motions preserve distances.
3. State that rigid motions preserve angle measures, so the image is congruent to the preimage.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Saying congruent only because figures look the same.
