AngleVectorFunction
This example demonstrates the property of the dot product being homogeneous: k(u·v) = (ku)·v = u·(kv) for any vectors u and v. Using GeoGebra commands such as Vector, Angle, Distance, and Translate, the example provides a visual understanding of this property. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. Vector(A, B) → u
  2. Vector(A, C) → v
  3. Angle(B, A, C) → α
  4. Distance(A, C) → f
  5. Distance(A, B) → g
  6. Translate(A, w) → A'
  7. Vector(A, A') → kv
  8. Translate(A, m) → A'_1
  9. Vector(A, A'_1) → ku
  10. Angle(C, A, A'_1) → β
  11. Angle(A', A, B) → γ

AI Drawing Prompt Reference

Draw two vectors u and v, and their dot product. Use points A, B, and C, with vector u from A to B and vector v from A to C. Change the lengths of vectors u and v to observe the homogeneity of the dot product, i.e., k(u·v) = (ku)·v = u·(kv).
