Question

Decide if the following triplets of points are collinear.
(1) [(-2, 5), (3, 3), (5, -1)]
(ii) [(4, -10), (2, 6), (4, 6)]
(Ans : (i) No (ii) Yes)
​

Answer 1

Part (i) the points are non collinear...Part (ii) the points are collinear

Step-by-step explanation:

To check whether the points are collinear or not just apply the distance formula and find the distance b/w the points and sum up the distances with smaller magnitude it should come equal to the 3rd distance.
