Vector Subtraction and Parallelogram Demo

This example demonstrates the geometric interpretation of vector subtraction using GeoGebra, visualizing the parallelogram rule for vector operations. Core math concepts include vectors, angles, two-dimensional vector arithmetic, and function graphing. The construction leverages commands like Polygon and Textfield, allowing dynamic adjustment of vector parameters with sliders and real-time updates of the parallelogram and resulting vector. Suitable for middle school students and above learning vectors and geometric constructions, as well as university-level physics education.
