Demonstrating Lines, Rays, and Segments

This GeoGebra example visually contrasts three fundamental types of geometric “lines”: lines, rays, and segments, emphasizing how endpoint constraints and directions affect their geometric meaning. It covers core concepts such as points, infinite lines, half-infinite rays starting from an endpoint, and finite line segments with two endpoints. Using the construction summary, the model creates many point objects (A, B, C, D, E, F, G, H, I, J) and then applies GeoGebra commands Line, Ray, and Segment to generate the corresponding geometric entities. The resulting diagram supports quick recognition of differences between infinite extension versus limited length and one-sided extension. Suitable for middle school to high school geometry lessons, concept teaching, and geometry construction practice.
