What is the definition of a ray

The video tutorial introduces basic geometric concepts, focusing on lines and rays. It explains that a line extends indefinitely in both directions and contains at least two points. The tutorial then transitions to defining a ray as a part of a line that extends indefinitely in one direction and has an endpoint. The instructor uses visual aids to reinforce these definitions and encourages students to write down the key points discussed.
