TriangleFunctionProbability & Statistics
This example demonstrates the dynamic changes of a triangle on a plane. It involves the calculation of the area of a triangle and random experiments. Using GeoGebra commands such as Line, Point, and Polygon, a dynamic triangle can be constructed and observed under different conditions. Suitable for middle and high school students to learn geometric transformations and probability statistics.

GeoGebra Commands & Parameters

  1. Line(A_1, B_1) → f
  2. Line(C_1, D_1) → g
  3. Point(g) → A
  4. Point(g) → C
  5. Point(f) → B
  6. Polygon(B, A, C) → poly1, f_1, g_1, e
  7. Point(f) → D
  8. Polygon(D, A, C) → poly2, f_2, h, e_1
