12200The nine-point conic
- Mar 1, 2006Dear All
We discussed the nine-point conic recently.
I have now put up a webpage giving very simple proofs
of most of the basic facts using barycentrics. The proof
that there is a conic circumscribed on any two cevian
triangles is about as short as the usual one, but does
not require the machinery of projective involutions.
