Exploring Points, Lines, and Planes in Geometry

This video tutorial covers the basics of geometry, focusing on points, lines, and planes as foundational elements. It explains the concepts of collinear and coplanar, and how to name lines and planes. The video also models geometric shapes and emphasizes the importance of precision in geometry. It concludes with practice problems to reinforce the concepts learned.
