Two Tangents from a Point on the Directrix of a Parabola Intersect at Right Angl

This example demonstrates that two tangents from a point on the directrix of a parabola intersect at right angles. Key mathematical concepts include the properties of parabolas and the geometric relationship between tangents. Using GeoGebra commands such as Point, Tangent, and Angle, one can observe this interesting geometric property. Suitable for high school mathematics education and learning.
