Q7 of 177 Page 23

Prove that the points and are the vertices of a right-angled triangle.

In a right angle triangle


Where CA is the hypotenuse


BC is the perpendicular and AB is the base


Vertices of the triangle are given below


A = (1, -1, 0), B = (4, -3, 1), C = (2, -4, 5)


So,







………..(1)


Similarly,






…………(2)






…………..(3)




35 = 14 + 21


35 = 35


LHS = RHS


So, these point form a right angle triangle
