dist = sqrt(pow((a2-a1), 2) + pow((b2-b1), 2));
return dist;
}Even though this wont compile at the moment I don't think the code is working, there must be a flaw in my logic or calculations somewhere.
The object of this code is to take 3 vertices and return whether the triangle is isosceles, equilateral or scalene.
It just wont return a value for me!
All help much appreciated. :)
