Congruence Transformation Example 2

This example demonstrates the congruence transformation phenomenon of polygons in three-dimensional space. It involves core mathematical concepts such as congruence, LCM and GCD, optimization problems, correlation, 3D vectors, and spheres. The construction uses GeoGebra commands to create points A, B, C, polygon poly1, and related vectors a, b, and a sphere c. It is suitable for high school and above learners to understand spatial geometric transformations and optimization problems.
