Problem 163 of 7
Explain congruence criterion ASA using rigid motions for triangles LMN and OPQ where angle L = angle O, angle M = angle P, and side LM = side OP.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
connect criterion to mapping one triangle onto another.
Hidden until you reveal it.
Criterion must be SSS, SAS, or ASA.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. State what information the criterion fixes.
2. Explain how a rigid motion can align the fixed parts.
3. Show that the remaining vertex or side is forced to match.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Circularly saying the criterion works because it proves congruence.
