Question

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

Answer 1

dear sir , 

A right triangle contains a right angle, so it must have two sides which are

perpendicular.
 
sir , If the slopes of two sides can be shown to be negative

reciprocals of each other, then it can be concluded that a right angle is

formed. If a triangle contains a right angle,

then it is a right triangle.

HOPE THIS HELPS YOU SIR ,

Answer 2

Slope =m = tan θ
=length of the opposite side of angle θ/length of adjacent side of the angle θ
