(b) A line segment
(c) A line

Answer:
(Coordinate Geometry)
Definition: A line which starts at a point with given coordinates, and goes off in a particular direction to infinity, possibly through a second point. Try this Adjust the ray below by dragging an orange dot and see how the ray AB behaves.
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints.
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints.
Answer:
A line can be named either using two points on the line (for example, AB←→AB↔ ) or simply by a letter, usually lowercase.
A line segment has two endpoints. It contains these endpoints and all the points of the line between them. You can measure the length of a segment, but not of a line.
A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray.
