External link suggestion for "Equivalence of Definitions of Ellipse"
Maybe you could consider adding a link on the page Equivalence of Definitions of Ellipse to a "pure" geometric proof that can be found here http://www.lucamoroni.it/ellipse-geometric-proof-equivalent-definitions-foci-directrix/ It's a different approach to showing the equivalence of the definition of the ellipse based on purely plane geometry arguments and I think it could fit well (as a complement) in the Ellipse page of Proof Wiki.


 * Alternatively you may wish to add the proof yourself -- we don't link to proofs, we include them complete.
