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?

Best ResponseYou've already chosen the best response.1you 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.

Best ResponseYou've already chosen the best response.1zero slope is horizontal, infinite slope is vertical. if they intersect, then by definition they would be at right angles, yeah?
