But draw the triangle (0,0)(1,0)(2,0)! Ofcourse the area is 0, because we have three points in one line.
Use (0,0), (2,3) and (4,1) to check.

Glad that hiddpolen helped you solve your problem.
Anyway, one comment on the condition.
return !(a+b<c || b+c<a || a+c<b || a == 0 || b == 0 || c == 0);This is actually the same as what I suggested earlier (add the = sign).
return !(a+b<=c || b+c<=a || a+c<=b);The reason is whenever a side of 3 points is 0, other 2 sides will always be the same regardless. I am not saying that doing the before is wrong. It is just a way of thinking when you do programming. It just make the code look cleaner and more succinct.

You are right, I see it now. Good suggestion, my thinking was twisted exactly the other way :)
