This example demonstrates how to observe the difference of vectors by moving the heads of vectors g and h. It involves basic vector concepts and how to construct vectors using GeoGebra commands. Commands such as Segment, Line, Intersect, Mirror are used to build the vector difference. Suitable for students from middle school and above to learn about vector concepts.

GeoGebra Commands & Parameters

  1. Segment(T, H_1) → h
  2. Segment(T, H_2) → g
  3. Line(H_2, h) → k
  4. Line(H_1, g) → l
  5. Intersect(k, l) → H_3
  6. Segment(T, H_3) → r_1
  7. Segment(H_2, H_3) → m
  8. Segment(H_1, H_3) → n
  9. Mirror(H_2, T) → H_4
  10. Segment(T, H_4) → negative_g
  11. Line(H_4, h) → q
  12. Line(H_1, negative_g) → s
  13. Intersect(q, s) → H_5
  14. Segment(H_4, H_5) → t
  15. Segment(H_5, H_1) → a_1
  16. Segment(T, H_5) → r
