This example demonstrates how to construct the vector equation of a line in three-dimensional space. It involves core math concepts like vectors, 3D coordinate geometry, and straight line equations. Key GeoGebra commands and objects used include Line, Vector, Point, with parameters like A, B, C, λ. Suitable for high school and above students to reinforce understanding and practice constructing vector equations in 3D.

AI Drawing Prompt Reference

Draw a line in 3D space using vectors A and B to define the direction of the line, construct line L1 through point A and vector AB, then construct vector b through point A and point D on line L1. Define origin O and point P, construct vector r through O and P, construct vector a through O and A, and construct vector v through O and B. Finally, construct line L2 through points A and B, construct vector v1 through origin O and point B, construct line L3 through points A and B, and construct vector v2 through origin O and point B.
