Full solution stays hidden until you ask for it.
1. Identify the transformation type.
2. Recall whether it preserves shape or only distorts it.
3. State whether angle measures remain equal.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Assuming only rigid motions preserve angles; dilations preserve angles too.
