Locus Intersection tangents and normals of focal chord

This resource has been marked as outstanding by a GeoGebra moderator.

As you move a point at one end of a focal chord, you trace out the loci of the intersection of the tangents and normals at the end of the focal chord. You can then attempt to match the locus of the intersection of normals with the equation of a parabola.
