Explain how slope is used to determine if a triangle is a right triangle?

Answer 1

well 2 lines are perpendicular if the product of there slopes is -1

perpendicular = right angle

Answer 2

let m1 = the slope of AB. let m2 = slope of BC. the relation between two orthogonal lines is that m1 = -1/m2. if m1 = -1/m2, then it is a right triangle

Answer 3

@urb0b thank you!
