Problem 124 of 7
Use coordinates M=-3, -2, N=-1, 0, O=-5, 0 to prove or disprove that the points form an isosceles triangle.
Using a hint is okay. It just tells the trainer to give you a little more review.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Compute squared lengths for all three sides.
2. Look for at least two equal side lengths.
3. Conclude whether the triangle is isosceles.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Comparing only x- or y-coordinate differences for diagonal sides.
