Collinearity and Points Relationship

The video tutorial explains the concept of collinearity using an analogy of co-workers. It describes how points that lie on the same line are considered collinear, using examples of points A, B, and C. The tutorial also discusses non-collinear points, exemplified by point D, which does not lie on the same line as the others. The video concludes with a summary of the collinearity concept.
