What is the difference between a line, a line segment, and a ray.

Line - Made up of two points with no thickness or width. It extends forever in both directions

Line Segment - A measurable part of a line that has two endpoints and end in both directions.

Ray - A line that extends forever in one direction, with an endpoint at the other end
