This example demonstrates how to create a projection using GeoGebra. Key mathematical concepts include vectors and angles. Commands such as Intersect, Vector, and OrthogonalLine are used to construct the projection effect. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. Intersect(xAxis, yAxis) → B
  2. Vector(B, C) → u
  3. Vector(B, A) → w
  4. OrthogonalLine(C, w) → c
  5. Line(B, A) → d
  6. Intersect(c, d) → D
  7. Vector(B, D) → v
  8. Segment(D, C) → e
  9. Angle(C, D, B) → angle1
  10. Angle(B, D, C) → angle2
