Lines, Planes, and Points Interaction Demo

This example demonstrates the interaction and positional relationships between lines, planes, and points in three-dimensional space. Key math concepts include spatial geometry, vector operations, point-line-plane relationships, and analytical geometry. Construction highlights involve commands/objects like text1, A, B, pic1, text2, C, D, pic2, text3 from GeoGebra for text annotations, line/point drawing, and image display. Suitable for high school and above students and teachers learning spatial geometry, vectors, and analytical geometry.
