Geometric Construction and Locus Demonstration of the First Definition of a Para
2019-07-31 02:55
This GeoGebra example dynamically demonstrates the first definition of a parabola through geometric construction. It includes a focus F and a directrix L, using the intersection of a perpendicular bisector and an orthogonal line to generate a locus. This visually illustrates the geometric property that any point on the parabola is equidistant from the focus and the directrix. Auxiliary elements li
