Symmetric Polygon Centroid & Vector Demo

This example demonstrates constructing symmetric polygons and calculating their centroids using GeoGebra, along with related vectors. Core math concepts include polygons, vectors, centroids, symmetry, and analytical geometry. Construction highlights involve commands like Point, Vector, Textfield, creating objects such as points C, A, B, centroid G1, and vector u. Suitable for high school and above students learning polygon properties, vector operations, and geometric constructions.
