This example demonstrates calculating the area of a quadrilateral by randomly generating its vertices. Key math concepts include the area calculation of a quadrilateral and random number generation. It uses commands like Random, RandomElement, Polygon, and Textfield in GeoGebra. Suitable for middle school and above students to learn geometric construction and probability statistics.

GeoGebra Commands & Parameters

  1. Random(-10, 10) → a
  2. RandomElement({-5, -4, -3, -2, -1, 1, 2, 3, 4, 5}) → c_1
  3. Random(-10, 10) → d_1
  4. Random(-15, 15) → d_2
  5. RandomElement({-5, -4, -3, -2, -1, 1, 2, 3, 4, 5}) → c
  6. Random(-10, 10) → b
  7. Random(-15, 15) → b_1
  8. Random(-15, 15) → a_1
  9. Polygon(C, D, E, F) → poly1, c_1, d, e_1, f_1
  10. Textfield() → InputBox1
  11. Textfield() → InputBox2
  12. Textfield() → InputBox3
