Question

14. To show that A, B and C are collinear which of the following is correct.
(a) AB + BC=AC (b) AC + CB = AB (c)BA + AC=BC and define "Collinear
points".
​

Answer 1

Step-by-step explanation:

We will discuss here how to prove the conditions of collinearity of three points. Collinear points: Three points A, B and C are said to be collinear if they lie on the same straight line. There points A, B and C will be collinear if AB + BC = AC as is clear from the adjoining figure
