This example demonstrates finding the intersection of two lines in three-dimensional space. Key mathematical concepts include vectors and line equations. Using GeoGebra commands such as Line, Vector, and Point, you can dynamically adjust the position of the lines. Suitable for high school and above students learning coordinate and solid geometry.

GeoGebra Commands & Parameters

  1. Line(A, B) → L_1
  2. Vector(A, B) → u
  3. Point(A_1, u) → D
  4. Vector(A_1, D) → b
  5. Vector(O, P) → r
  6. Vector(O, A) → a
  7. Vector(O, B) → v
  8. Line(E, C) → i
  9. Vector(O, C) → c
  10. Vector(C, E) → ce
