Differentiating Lines, Line Segments, and Rays

The video tutorial explains the differences between lines, line segments, and rays. It begins with an introduction to these geometric concepts, followed by a detailed explanation of each. Lines are described as extending infinitely in both directions, represented by arrows. Line segments are defined as parts of lines with specific start and end points. Rays are introduced as having a starting point and extending infinitely in one direction. The tutorial aims to clarify these concepts and highlight their differences.

What symbolizes that a line extends indefinitely in both directions?

• No symbols at the ends

• A single arrow at one end

• Arrows at each end

• A dot at each end
