Question

three points a b and c exist in space such that b is between a and C it is known that AB = 7 , BC= 4 and AC = 9 . Ar epoints a b and c Collinear? give a written explanation supported by mathematical evidence for your answer.

Answer 1

Points are collinear if they are in the same line.

So:

AB+BC = AC

Replacing with the values given:

7+4 = 9

11 =9 False

A,b, and c aren't collinear.
