Full solution stays hidden until you ask for it.
1. Identify the dilation scale factor in a similarity transformation.
2. Note rigid motions do not change length.
3. Conclude all corresponding side ratios are equal.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Claiming similarity means side lengths are equal unless k=1.
