PolygonCoordinate GeometryGeometric Construction
This example demonstrates the properties of a parallelogram, including medians, circumcircle, and area. Using GeoGebra commands such as Line, Polygon, Distance, etc., it visually illustrates the geometric features of a parallelogram. Suitable for middle and high school students learning geometry and coordinate geometry.
