This example demonstrates the effect of two reflections. By using reflection transformations, you can observe how a figure changes after two reflections in different directions. Key mathematical concepts include reflection transformations and geometric transformations. It utilizes commands such as Polygon, Line, and Mirror in GeoGebra. Suitable for middle school and above students to learn about geometric transformations.
