Parabola Pedal Curve

On the Directrix, the Pedal Curve of a Parabola is a Strophoid (topleft). On the foot of the Directrix, it is a Right Strophoid (top middle). Onreflection of the Focus in the Directrix, it is a Maclaurin Trisectrix (topright). On the Vertex, it is a Cissoid of Diocles (bottom left). On the Focus, it isa straight line (bottom right).
