Problem 7 of 7
Use SSS to prove triangles congruent from side data ABC=DEF=2y with y=4, BC=EF=9, AC=DF=11.
Hints
Using a hint is okay. It just tells the trainer to give you a little more review.

Full solution stays hidden until you ask for it.
1. Match the corresponding sides.
2. Verify all three pairs of sides are congruent.
3. Conclude triangle congruence by SSS.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
SSS if fewer than three side pairs are established.
