A Ray
segment
Half a straight line is called a "ray." A ray starts at a specific point, known as the endpoint, and extends infinitely in one direction. Unlike a line segment, which has two endpoints, a ray has only one endpoint and continues indefinitely.
They are alike because a ray is part of a line, a segment is part of a line, and a line is basically a line. They are different because a segment has two end points; a ray has one, and a line is a group of points on a straight path that extends to infinity like a ray extends to infinity in one direction
A half line is a geometric concept that consists of a point called the endpoint and all the points extending infinitely in one direction from that endpoint. It can be visualized as starting from a specific point and continuing indefinitely along a straight path. Unlike a line segment, which has two endpoints, or a full line, which extends in both directions, a half line only extends in one direction from its designated endpoint.
A ray
a straight line that extends for a point forever in one direction
This is called a "ray". (It is equal to one half of a line.)

a half-line with a designated end point which extends in only one direction without stopping
- A line has no ends and extends forever in both directions.- A ray has one end and extends forever in the other direction.- A line segment has two ends and a definite length.
A Ray.
A single ray is a straight line that extends infinitely in one direction from a starting point, known as the endpoint. In geometry, it is often represented as a line segment with a single arrowhead at one end, indicating the direction in which it extends. Rays are fundamental in various geometric concepts and are commonly used to describe angles and light paths.
