This example demonstrates the properties of rectangles and rhombuses, involving symmetry and similarity in geometry. Using GeoGebra commands such as Line, Intersect, and Midpoint, one can construct rectangles and rhombuses and explore their properties. Suitable for middle and high school students to learn geometric construction and property exploration.
