Question

4) Area of a triangle is zero then the points
are​

Answer 1

Answer:

If the area of a triangle was equal to zero, then there would be no triangle, the points would be collinear (on a line). We can use that fact to develop a test for collinear points. If the area of a triangle is zero, the points are collinear.
