This video tutorial explains the differences between lines, rays, and line segments. It begins with an introduction to these geometric concepts, followed by detailed explanations and examples of each. The video also covers the notation used to represent lines, rays, and segments. Finally, it includes practice questions to help viewers identify and differentiate between these geometric figures.

What is a line segment?

• A path that extends infinitely in one direction

• A path that extends infinitely in both directions

• A straight path with a beginning and an end

• A curved path with no endpoints
