Understanding Ray and Its Endpoints
A ray is a fundamental concept in geometry, often introduced in Class 6.
Definition of a Ray
- A ray is a part of a line that starts at a specific point and extends infinitely in one direction.
- It has one endpoint, which is the starting point of the ray.
Key Characteristics of a Ray
- One Endpoint:
- A ray has a single endpoint, which marks the beginning of the ray.
- Infinite Length:
- After the endpoint, the ray continues indefinitely in one direction without any end.
Visual Representation of a Ray
- A ray can be represented graphically as follows:
- Start with a point (the endpoint).
- Draw a straight line extending from the point in one direction, with an arrow indicating that it continues indefinitely.
Example of a Ray
- For instance, if we name the endpoint as point A, and the ray extends towards point B, we can denote it as ray AB.
- In this example:
- A is the endpoint.
- The ray continues beyond point B.
Conclusion
- In summary, a ray has one endpoint, which is crucial in differentiating it from other geometric figures such as lines (which have two endpoints) and line segments (which have two endpoints as well). Understanding rays helps build a solid foundation for further studies in geometry.

Ray has one end point or starting point.
