Pythagorean Inequalities Theorem Demo

This example demonstrates the Pythagorean Inequalities Theorem in three-dimensional space. It involves core mathematical concepts such as inequalities, median line, volume, 3D vectors, rectangle, and upper/lower sum or Riemann sum. The construction uses commands like Polygon and Angle, with objects A, B, C, t1, c, a, b, α. Suitable for high school and above students to understand the relationship between spatial geometry and inequalities.
