Difference between Line, Line segment and Ray

Here is the difference between a line, a line segment, and a ray:

1. Line:

• Definition: A line is a straight one-dimensional figure that extends infinitely in both directions.
• Key Features:
  • No endpoints.
  • Infinite length.
  • Represented with arrows on both ends (e.g., ↔AB).
• Example: A straight path that has no end.

2. Line Segment:

• Definition: A line segment is a part of a line that has two definite endpoints.
• Key Features:
  • Has a fixed length.
  • Does not extend beyond its endpoints.
  • Represented by the endpoints (e.g., [AB]).
• Example: A stick of fixed length.

3. Ray:

• Definition: A ray is a part of a line that starts at a specific point (called the endpoint) and extends infinitely in one direction.
• Key Features:
  • One endpoint.
  • Extends infinitely in one direction.
  • Represented with an arrow at one end (e.g., →AB).
• Example: A sunbeam that starts at the sun and extends outward.
