I'm developer TrianCal (online triangle calculator). I do not get the following formulas : The minimum perimeter of any triangle (abc), given the heights corresponding to the a and bsides. The maximum height corresponding to the side b of any triangle (abc), given the value of its perimeter and height corresponding to the aside. Jesus please send me a email to: jsdcorreo@gmail.com subject: Triancal (Calculadora de triangulos online)

Perimeter $P \lt 2(a+b)$ since the angle between the given sides is less than $\pi$ radians. You can rearrange this for the other formula.

Well, since the base of the triangle could be anything between zero and "infinity", the perimeter is going to be between twice the height and "infinity".
