Problem 121 of 7
Explain why translation by vector <2,7> maps triangle JKL to triangle MNO establishes triangle congruence.
Using a hint is okay. It just tells the trainer to give you a little more review.

reason that translation preserves side lengths and angles.
Hidden until you reveal it.
Translation must map one triangle to the other or its image.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify the translation vector.
2. State that every point moves by that same vector.
3. Because distances and angles are unchanged, the triangles are congruent.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Claiming translation changes size.
