This example demonstrates constructing geometric figures in GeoGebra to illustrate the generalized definition of symmetry number. Core math concepts include centroid, circle, geometry, symmetry, congruence, and similarity transformation. Construction highlights the use of Circle, Point, Segment, and Barycenter commands. Suitable for high school mathematics education to understand geometric transformations and symmetry.

AI Drawing Prompt Reference

Draw a circle with center Z. Place multiple points on the circumference, including P, O, N, M, L, K, B, C, D, E, F, G, H, I, J, and A. From the center Z, draw line segments to each of these points, creating a radial pattern. Finally, compute and mark the centroid (geometric center) of all these circumference points. The figure shows a circle with many radii and the central point of the polygon formed by the endpoints.
