Red Parabola

This example demonstrates the geometric construction of a red parabola. A parabola is a conic section defined as the set of points equidistant from a fixed point (focus) and a fixed line (directrix). Using GeoGebra, this example visually illustrates the construction of a parabola using points, segments, and functions. The construction commands include points, segments, and other basic objects, suitable for middle school and above students to learn about the properties and geometric construction of parabolas.
