This example demonstrates the geometric construction of the Giugiuc parabola. Key mathematical concepts include parabola, circumcircle, rectangle, correlation, parallelogram, and equilateral triangles. Using GeoGebra commands such as Line, Parabola, Point, Tangent, Intersect, Polygon, Circle, Center, Segment, Angle, Distance, and OrthogonalLine, complex geometric figures can be constructed. Suitable for high school mathematics education and research.
