Problem 97 of 7
Use dilation to reason about parallel relationships in triangle ABC dilated from A maps segment BC to B'C'.
Using a hint is okay. It just tells the trainer to give you a little more review.

connect transformation behavior to geometry theorem.
Hidden until you reveal it.
Conclusion must connect dilation line behavior to a geometric parallel relationship.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify the dilation center.
2. Determine whether the relevant line passes through the center.
3. Use same-line or parallel-image behavior to state the relationship.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Claiming dilation alone proves perpendicularity.
