We can use our distance formula to ...
How to show that points are collinear
Did you know?
WebUsing the concept of distance between two points, show that the points A (5, -2), B (4, -1) and C (1, 2) are collinear. Solution : We know the distance between the two points (x1, y1) and (x2, y2) is d = √ [ (x2 - x1)2 + (y2 - y1)2] Let us find the lengths AB, BC and AC using the above distance formula. AB = √ [ (4 - 5)2 + (-1 + 2) 2] Web41K views 11 years ago Class 11, Geometry In this example of a 3-D geometry, we show you one of the method of proving collinearity of three points using distance formula.
