Full solution stays hidden until you ask for it.
1. State what equal angles guarantee.
2. Explain that side lengths may be scaled.
3. Conclude AA is sufficient for similarity, not congruence.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Claiming AA proves congruence.
