[algogeeks] Re: No of triangles
@Payel: I think you are asking how many triangles you can form with integer sides and perimeter n. See http://oeis.org/A005044 for several formulas and for references.

Given n, how many will be possible? -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

[algogeeks] Re: same perimeter triangles
the distance ap, bp and cp are the unknowns. we can get 3 simultaneous equations based on the condition that the permeters are same. ie, ab+ap= bc+pc ... and so on . 3 unknows and 3 equations = we can find the unknowns. once we find the distance ap and bp, finding the point 'p' is again solved by two simultaneous equations On Jun 1, 6:01 pm, Terry [EMAIL PROTECTED] wrote: Hi, This one's puzzling me since a while.

[algogeeks] Re: same perimeter triangles
Not really. The third equation is trivial and can be derived from other two. So in fact we have two equations and 3 unknowns.
