Dilation of Regular Polygons in a Ring Pattern

① This example demonstrates a ring of regular polygons that are dynamically dilated to create a symmetric pattern. ② Core mathematical concepts include properties of regular polygons, similarity transformations and dilation ratios, sequence‑generated discrete point sets, and the symmetry of circular arrangements. ③ Construction highlights: the Sequence command creates parameters n, r and the point list dots; the Polygon command builds the base polygon poly1; the ring object then applies dilation and replication to form the full ring. ④ Suitable for high‑school geometry, college transformation geometry courses, and as a GeoGebra teaching resource.
