If three or more points do not lie on the same straight line, then they are said to be non-collinear points. If any point of all the points is not on the same line, then as a group they are non-collinear points. For non-collinear points, the area of the triangle joined by the three points will always be greater than 0.
What is non collinear?
: not collinear: a : not lying or acting in the same straight line noncollinear forces. b : not having a straight line in common noncollinear planes.
