SOLUTION: I need to figure out if any of these points form a right triangle. They are (0,0) (-5,2) (2,-5) So far, I have drawn my triangle on a graph and named (0,0) A; (-5,2) B and (2,-5) C

Question 1027167: I need to figure out if any of these points form a right triangle. They are (0,0) (-5,2) (2,-5) So far, I have drawn my triangle on a graph and named (0,0) A; (-5,2) B and (2,-5) C. I found the distance from AB is 2/-5, the distance from AC is -5/2, and the distance from BC is -1. How do I know if any of these points form a right triangle or not? Thanks so much for taking your time to help!!

If a right triangle, the longest side should be the hypotenuse. You can plug in the distance values you found into Pythagorean Theorem formula. If the statement is true, then you have a right triangle. If the statement is false, the triangle is not a right triangle.
