# Show that the fol

To prove: the 3 points are collinear.

Formula:

The distance between two points (x1,y1,z1) and (x2,y2,z2) is given by

D= Here,

(x1,y1,z1)= (-2, 3, 5)

(x2,y2,z2)= (1, 2, 3)

(x3,y3,z3)= (7, 0, -1)

Length AB = = = = = Length BC = = = = = = 2 Length AC = = = = = = 3 AB + BC = + 2 =3 = AC

Therefore A, B, C are collinear. Rate this question :
