Problem 72 of 7
Prove the quadrilateral type using coordinates for K(0,0), L(2,1), M(1,3), N(-1,2).
Using a hint is okay. It just tells the trainer to give you a little more review.

combine distance, slope, and midpoint evidence.
Hidden until you reveal it.
Proof must combine distance, slope, or midpoint evidence sufficient for the quadrilateral type.

Full solution stays hidden until you ask for it.
1. Compute slopes, lengths, or midpoints as needed.
2. Match evidence to a quadrilateral definition or theorem.
3. State the proven quadrilateral type.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
A stronger classification without sufficient evidence.
