Drawing Parabola in Three Ways

This example demonstrates three different methods for constructing a parabola. It involves core mathematical concepts such as the definition of a parabola, focus, directrix, tangent, and integral. The construction uses GeoGebra commands/objects like Point, Line, Segment, LineBisector, OrthogonalLine, Intersect, and Angle. Suitable for high school and above students to understand the geometric properties and algebraic expressions of parabolas.
