Naming the rays in a given figure

The video tutorial explains the concept of rays in geometry, which are portions of a line with an endpoint that extends infinitely in one direction. It demonstrates how to label rays using different endpoints (L, M, and P) and points on a line. The tutorial emphasizes the importance of writing the endpoint first when labeling rays and provides examples of different ways to label the same ray.
