3D Vectors and Triangle Statistical Characteristics Demo

This example demonstrates the relationship between 3D vectors and the statistical characteristics of equilateral triangles. Core math concepts include 3D vector operations, properties of equilateral triangles, and statistical feature calculations. Construction highlights use of GeoGebra commands like Point, Vector, Textfield to build objects such as vectors k, h, m and triangle ABC, with sliders for dynamic statistical visualization. Suitable for high school and above learning solid geometry and vector analysis.
