Points, Lines, and Planes Geometry Demo

This example demonstrates the fundamental spatial relationships among points, lines, and planes in three‑dimensional geometry. Core concepts include points, segments, vectors, polygons, planes, and basics of coordinate and solid geometry. Construction uses GeoGebra commands Point, Segment, Vector, Polygon to create objects A, B, C, D, E, F, G, lines Line and Line_1, vectors u and v, planes Plane and PlaneText, and polygon poly1. It is suitable for high‑school solid geometry lessons, introductory university geometry courses, and geometric construction practice.
