@AGoogler The bet was about who will finish with a higher ranking in the ICC T20 2014. Since I was the intelligent one, I choose SL, and he was an emotional one, he chose India. It turns out that both the teams reached the final! But of course, I won. And he forgot the bet! Now he will receive the penalty.
@AGoogler As for the formula, its very simple. And infact, its quite common as well, I thought you ll know it. But it works for every convex quad. I ll give a hint..
you just don't see the messages of the people you have ignored
(and ironically, I stopped in here to check if mods could talk without privs in a room hosted on a site they weren't a mod on, so I killed two birds with one stone)
