Focus and Directrix Connections Demo

This example demonstrates the geometric relationships between the focus and directrix of ellipses, hyperbolas, and parabolas. It involves core math concepts like conic sections' definitions, focus properties, directrix relationships, and analytical geometry. Construction highlights include using GeoGebra commands such as Line, OrthogonalLine, Intersect, Segment, and Circle. Suitable for high school and above students to understand the geometric essence and properties of conic sections and enhance analytical geometry drawing skills.
