Gergonne and Nigel point.

 Problema a mai fost propusa cu ceva timp in urma.  La rezolvare apare conditia ceruta dar nedemonstrata,  ceea ce ,  in cazul acestei probleme, este echivalent cu nimic.   Asa ca rezolvarea de atunci o trecem la enunt.

Ge - punctul lui Gergonne
N - punctul lui Nagel
Notam cu a, b, c lungimea segmentelor [BC], [CA] respectiv [AB].
Conditia de indeplinit pentru ca (GeN) paralel cu (BC) este a*(b+c)=b^2+c^2

PS. am readus problema in atentie nu numai fiindca e interesanta si ca e o mica obsesie de-a mea ci si pentru ca exista zvonuri ca cineva a gasit rezolvarea :D
