To check the collinearity of three points, find the distance between pairs of points.
To check the collinearity of three points, find the distance between pairs of points. That means, find AB, BC and CA. If the sum of any two lengths is equal to the third one, then they are collinear. In this case, AB = 10, BC = 10 and CA = 20. That is, AB + BC = CA. Hence they are collinear.
