    Re: Symmedian point -earliest reference in navigation

    Thanks Herbert (I was just being a bit slow there). I have attached the two pages. It is quite clear on p38 and 39 even for people who can only just read mathematical French like me. Notice that he exhibits the trilinear coordinates a:b:c for the symmedian point, but he doesn't seem to give any reference to indicate it is already known in the literature, so he may have reinvented it.
