Exploring Points, Lines, and Planes in Geometry

This video tutorial provides an overview of points, lines, and planes in geometry. It explains how to identify collinear and coplanar points, name planes using three points, and name lines using two points. The tutorial also covers the concept of opposite rays and how to identify them. Examples are provided throughout to illustrate these concepts.
