Geometric Definition and Locus Construction of a Parabola

2014-06-23 08:43
This example demonstrates the classic geometric definition of a parabola, where the distance from a moving point to the focus equals its distance to the directrix. Using GeoGebra commands such as orthogonal lines, perpendicular bisectors, and intersections, it dynamically tracks the moving point satisfying the equidistant condition to generate the parabola's locus. This construction intuitively il
