Blue parabola: = focus - defines the position of the directrix.
Red parabola: = focus - defines the position of the directrix.
Drag the foci and move the directrices to explore the number of intersection points of the two orthogonal parabolas.
Observe the special position of the intersection points when they are exactly 4.
Can you prove that property?
