Problem 116 of 7
Identify why proof claim Two circles are congruent if one can be obtained from the other by a dilation. confuses congruence and similarity.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
distinguish congruence from similarity.
Hidden until you reveal it.
Claim must contain congruence/similarity or transformation confusion.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify whether the claim is about shape or size.
2. Recall congruence uses rigid motions and same radius.
3. Recall similarity allows dilation and different radii.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Treating dilation as a congruence transformation.
