Tracing of Parabola via Focus-Directrix Property

This GeoGebra applet demonstrates the locus definition of a parabola, where the distance from a moving point to the focus equals its distance to the directrix. Key concepts include parabola properties, focus-directrix definition, and distance measurement. Construction utilizes commands like Point, OrthogonalLine, Intersect, and Distance to visualize the geometric constraint dynamically. Ideal for high school geometry classes, calculus preparation, or self-study on conic sections, providing an interactive way to verify the fundamental property of parabolas.
