I mean any pair of distinct vertices. The idea is basically the same as >>9404048 but you also check for intersections and continue the lines past vertices if possible.

I would think that the method works. The attached picture shows the simplified problem; if there exists a case in which AB - which passes through only one vertex - is the longest line, then the method will not work. However, in these cases either CD or EF should(?) be longer. I tried applying cosine rule and got something, but couldn't quite complete the proof...
