Question

how to find collinear? in co- ordinate geometry​

Answer 1

Just see if the area of the triangle that the points are forming are equal to zero or not.

If the area of the triangle is zero, then the points are collinear. If not, then they are non-collinear.

Hope this helps. Have a good day.

Answer 2

if we have given three points like A(5,6),B(-2,3) and C(6,8) and we have to find that they are collinear so we have to find that

AB + BC =CA or not.

if yes so they are collinear.
and the other method is if their area of triangle is equal to zero means they are collinear.

hope it help u....
