A ray.
It is called a Ray.
The point at the beginning of a ray is called the "endpoint." A ray is a part of a line that starts at this endpoint and extends infinitely in one direction. The endpoint is crucial as it defines where the ray begins, distinguishing it from a line segment, which has two endpoints.
It is called as a plain.
A plane?
A flat extending endlessly in all directions is called a plane.
It is called a Ray.
It's called a Ray.
This is called a "ray". (It is equal to one half of a line.)

A part of a line that extends in one direction with one endpoint is called a ray.
Two rays with the same endpoint form an angle. A ray is a part of a line that starts at a particular point and extends infinitely in one direction. When two rays share the same endpoint, they create an angle that is measured by the amount of rotation from one ray to the other. The common endpoint is called the vertex of the angle.
That, my friend, is called a ray. A segment is when a line has two definite endpoints, so it can't be that. And a line has no endpoints, so that is not it either. The ray, as you specified in your question, has one endpoint, and extends forever in one direction. Hope this has been of help. :)
A line is a straight path that extends infinitely or endlessly in opposite directions. A straight path that joins two points is called a line segment.
A plane?
It is called a line segement
The end would be called a point or an endpoint. It only has one end since it is infinite in the other direction.
