What does colinear and coplanar mean

The video tutorial provides an introduction to the concepts of collinear and coplanar points and lines in geometry. It explains that collinear points lie on the same line, while coplanar points lie on the same plane. The tutorial includes examples to illustrate these concepts, such as points A, B, and C being collinear, and points on plane P being coplanar. It also discusses non-collinear and non-coplanar points and lines, and explores perpendicular planes and lines. The video concludes with a review of the key concepts discussed.
