I need to prove that A(12, 5) B(12, 5) and C(12, 5) Is a right triangle. I know two adjacent angles need to be perpendicular but the slopes are 10/0 and 0/24 which are not negative reciprocals?

Can you explain with the coordinates I have placed because the slopes are not negative reciporicals?

Ok, but Im supposed to prove that it is a right triangle by the slopes?

you have 3 points, so you can find the slopes of the lines connecting all three. you can also use the points, and the slopes you have found, to find the equations of the lines.

SO my slopes are acuually negaitve reciporicals? 10/0 and 0/24

zero slope is horizontal, infinite slope is vertical. if they intersect, then by definition they would be at right angles, yeah?
