This example demonstrates a simple spinner with an animated spin triggered by a button, useful for probability simulations. Core math concepts include probability & statistics, random experiments, and geometric transformations. Construction highlights the use of GeoGebra commands/objects like RandomUniform, Vector, Circle, Point, and CircleSector. Ideal for middle school and above learning probability or as a math experiment tool.

GeoGebra Commands & Parameters

  1. RandomUniform(3600, 3960) → a
  2. Vector(A) → u
  3. Circle((0, 0), 1.3) → d

  5. Point(d) → C
  6. Point(d) → D
  7. Point(d) → E
  8. Point(d) → F
  9. Point(d) → G
  10. CircleSector(H, G, B) → e
  11. CircleSector(H, B, C) → f
  12. CircleSector(H, C, D) → g
  13. CircleSector(H, D, F) → h
  14. CircleSector(H, F, E) → k
  15. CircleSector(H, E, G) → p

AI Drawing Prompt Reference

Draw a simple spinner with a central circle and seven evenly spaced points around its circumference. Connect each point to the center to form colored扇形区域, and animate the spinner to rotate with a button, demonstrating probability simulation.
