Random Rectangle Construction

This example demonstrates the dynamic process of constructing rectangles through randomly generated points, exploring its connection with fractal geometry and stochastic processes. Core mathematical concepts include polygon construction, trigonometric function application, stochastic process simulation, and expected value calculation. Key GeoGebra commands used are Polygon for objects A, B, C, D, poly1, and parameters a, b, c, d for control. Suitable for high school and above learners to understand the application of stochastic processes in geometric construction and the manifestation of fractal ideas.
