VectorCoordinate GeometryGeometric Construction
This example demonstrates the linear combination of 2D vectors and its application in geometric figures. Core math concepts include vector operations, linear combinations, orthocenter, similarity transformations, and isosceles triangles. GeoGebra commands like Intersect, Vector, Line, and Midpoint are used in construction. Suitable for high school mathematics teaching to understand the connection between vectors and geometric transformations.

  2. Vector(A, B) → u
  3. Vector(A, C) → v
  4. Intersect(xAxis, yAxis) → D
  5. Line(C', w) → f
  6. Line(B', p) → g
  7. Intersect(f, g) → E
  8. Vector(D, E) → c
  9. Vector(B', E) → d
  10. Midpoint(B', D) → G
  11. Midpoint(D, E) → H
  12. Midpoint(B, A) → I
  13. Midpoint(A, C) → J

AI Drawing Prompt Reference

Draw a linear combination of vectors u and v, where u goes from point A to B and v goes from point A to C. Construct lines f and g passing through points C' and B', respectively. Lines f and g intersect at point E, with vector c from D to E and vector d from B' to E. Find the midpoints G and H of D and E, and I and J of B and A, and A and C. Finally, find the midpoint F of B' and E.
