Geometric Construction of a Parabola: Locus from Focus and Directrix

This example demonstrates the geometric construction of a parabola using its focus and directrix. By constructing the perpendicular bisector and orthogonal lines, the intersection points are traced to generate the parabolic locus. It visually illustrates the geometric definition of a parabola—where any point on the curve is equidistant from the focus and the directrix—making it ideal for teaching
