What is a line segment and ray

The video tutorial explains the concepts of lines, segments, and rays in geometry. A line is defined as an infinite set of points, represented by two points with arrows indicating its indefinite extension. A segment is a part of a line with two endpoints, containing infinite points between them but not extending beyond the endpoints. A ray combines aspects of a line and a segment, starting at an endpoint and extending indefinitely in one direction. The tutorial emphasizes the notation and properties of each geometric figure.
