Philoid · Accepted Answer

If Three points (a,b), (c,d), (e,f) are collinear then the area formed by the triangle by the three points is zero.

Area of a triangle = ...(1)

1. area =

Hence the points are collinear.

2. area =

Hence the points are collinear

3. area =

Hence the points are not collinear
