Planes Intersecting Demo by Brendon
Loading the math board and drawing, please wait…
This example demonstrates the intersection of three planes in 3D space, visually showing the formation and variation of the intersection line. Core math concepts include spatial geometry, plane equations, vector cross product, and point-line-plane relationships. The construction uses points A, P_1, P_2, P_3 to build three planes and calculate their intersection line. Suitable for high school and above learning solid geometry, spatial vectors, and geometric intuition, or university introductory geometry courses.

AI Drawing Prompt Reference
Draw the intersection line of three planes. First, create point A with coordinates (1, 2, 3) in 3D space, then define three planes P1, P2, and P3 with normal vectors (-1, 1, 3), (0, 1, 6), and (1, 1) respectively, and finally show the intersection line of these three planes.
