This example demonstrates p2mm symmetry. Key mathematical concepts include symmetry, reflection transformations, and geometric construction. Using GeoGebra commands such as Line, OrthogonalLine, Point, and Mirror, the construction of p2mm symmetric figures is illustrated. Suitable for middle school students and teachers to understand the concepts of symmetry and reflection transformations.
