Problem 24 of 7
Decide whether figures are congruent by reflection across y=-1.
Using a hint is okay. It just tells the trainer to give you a little more review.

verify mirror image across a line.
Hidden until you reveal it.
Reflection line must be specified and vertex correspondences must be testable.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Reflect each preimage vertex across the stated line.
2. Compare reflected points to corresponding image vertices.
3. If every vertex matches, reflection establishes congruence.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Yes if even one vertex is not the correct mirror image.
