The document defines key geometric terms including point, line, plane, line segment, and ray. It provides examples for each term. A point is an exact location named with a capital letter. A line is a straight path extending indefinitely in two directions named using two points on the line. A plane is a flat surface extending indefinitely in all directions named using three non-collinear points. A line segment has two endpoints and all points between them, named using the endpoints. A ray has one endpoint and extends indefinitely in one direction from that point, named using the endpoint and another point on the ray.
This will help you in differentiating subsets of a line such as line segments, ray and opposite rays. Also in finding the number of line segments and rays in a given line.
