Problem 12 of 7
Prove the side-splitter theorem in A transversal line segment parallel to one side of a triangle, cutting the other two sides.
Using a hint is okay. It just tells the trainer to give you a little more review.

show parallel line creates proportional segments.
Hidden until you reveal it.
Proof must show the parallel segment creates similar triangles and proportional side segments.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Use parallel-line angle relationships to prove triangle similarity.
2. Write corresponding side proportions.
3. Translate proportions to the split side segments.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Stating side proportions without justifying similarity.
