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.
A part of a line that extends endlessly in only one direction is called a "ray." It has a fixed starting point, known as the endpoint, and continues infinitely in one direction. Rays are commonly used in geometry to represent various concepts, including angles and light paths. They are typically depicted with a point and an arrow to indicate the direction of extension.
displacement
The direction and distance from the starting point to the ending point is referred to as "displacement." Displacement is a vector quantity that accounts for both the shortest straight-line distance between two points and the direction of that line. It differs from distance, which measures the total path traveled regardless of direction.
true
A ray has one endpoint and continues indefinitely in one direction.
A half line is a geometric concept that extends infinitely in one direction from a designated endpoint. This endpoint is considered the starting point of the half line, while the opposite direction continues indefinitely without terminating. In essence, it combines a fixed point with an unbounded extension, making it a key element in various mathematical and geometric contexts.
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.
