That type of line would be called a ray.
displacement
A line that goes on forever in both directions is a line. One that starts at one point and continues forever in the other direction is a ray, and one that has two definite ends is a line segment.
A ray.
a line segment
then it is not a line it is a ray. line go on and on without stopping in both directions.
A ray.
It is called a ray.
line
Ray - A ray is part of a line that has one endpoint. It continues in one direction without ending.
displacement
true
A ray has one endpoint and continues indefinitely in one direction.
It could be a displacement vector.
The distance and direction of an object from the starting point is called displacement. Displacement is a vector quantity that represents the straight line distance between the initial and final position of an object, along with the direction from the starting point to the endpoint.
A displacement vector describes the length and direction of movement of an object from its starting point. It represents the straight-line distance and direction between the initial and final positions of the object.
A ray in geometry is a line with a single endpoint and extends indefinitely in one specified direction.
a line. starting from one point and going on as long as it needs to go on. or it could go on forever. it needs a start and a finish...
