Collinear and Coplanar Points

The video tutorial introduces the concepts of collinear and coplanar points, explaining that collinear points lie on the same line, while coplanar points lie on the same plane. Using a cube and a triangular prism as examples, the video demonstrates how to identify planes, collinear points, and coplanar points within these shapes. It also explores the relationship between lines and planes, providing practical examples and questions to enhance understanding.
