What are coplanar points

The video tutorial explains the concepts of collinear and coplanar points in geometry. It describes how collinear points lie on the same line, while coplanar points lie on the same plane. The teacher uses a box or a sheet of paper as a metaphor for a plane, which requires at least three points. The lesson includes examples to illustrate these concepts and concludes with a reminder about homework.
