This example demonstrates the properties of a rhombus. Key mathematical concepts include the definition of a rhombus, relationships between angles and sides. Using GeoGebra commands such as Circle, Intersect, Polygon, etc., dynamic exploration of the geometric properties of a rhombus is possible. Suitable for middle school and above students or teachers.
