Question

Does anyone know the best software to make a scalene triangle using 3 predefined values?

Answer 1

kitweb,
It is not too difficult in Illustrator.
Presuming the values are the side lengths, you may turn on the Smart Guides and:
1) Create a circle with its centre at X=Y=0 and with its radius equalling the first side length;
2) Create another circle with its centre at X equalling the second side length and Y = 0, and with its radius equalling the third side length;
3) With the Pen Tool click at the centres of the circles (Smart Guides say centre), then at one of the intersections of the circles (Smart Guides say intersect), then back at the first centre;
4) Delete the circles, and if needed Object>Transform>Rotate/Reflect/Move/whatever for the right orientation/position.
Obviously, you may use any order of the predefined sidelengths from the beginning.
