TriangleTransformationGeometric Construction
This example demonstrates how to construct a triangle using rotation and angles. Key mathematical concepts include geometric construction and transformation. Using GeoGebra commands such as Segment, Rotate, and Angle, specific triangles can be constructed. Suitable for middle school and above students learning geometric construction and transformation.

GeoGebra Commands & Parameters

  1. Segment(A_1, B_1) → f
  2. Rotate(D, 42°, C) → D'
  3. Angle(D, C, D') → A
  4. Rotate(F, 98°, E) → F'
  5. Angle(F, E, F') → B
  6. Ray(E, F) → g
  7. Ray(E, F') → h
  8. Ray(C, D) → i
  9. Ray(C, D') → j
  10. Ray(C, D) → k
  11. Ray(E, F) → l
