A line with a single endpoint going infinitely in another direction is a ray. The symbol for a ray is → . It is named for its endpoint and any other point located on it.
A line segment is a portion of a line. It has length. It has two endpoints. A ray has only one endpoint. It has infinite length in one direction.
It has two endpoints. A ray has one endpoint.
By definition a line has no endpoint as it can extend to negative and positive infinity. A ray has one endpoint and a segment has two endpoints.

A ray.
In geometry, a line has no endpoints. If it has one endpoint and continues infinitely, it is a ray. If it has two endpoints, it is a line segment. If it has one end that approaches but never reaches a point, it is a half line.
A ray begins at an endpoint and extends in only one direction.A half line does not include the endpoint.

The segment you describe is the radius of the circle.
