Problem 117 of 7
Use coordinates U=-1, -1, V=2, -2, W=0, 2 to prove or disprove that the points form a right triangle.
Using a hint is okay. It just tells the trainer to give you a little more review.

use slopes or side lengths/Pythagorean relationship.
Hidden until you reveal it.
Points must be noncollinear unless disproving a triangle as part of the evidence.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Compute slopes or squared side lengths.
2. Check for perpendicular sides or the Pythagorean relationship.
3. State whether the triangle is right with evidence.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Relying on graph appearance without calculations.
