Quote:.. How can I make a mathematically correct triangle using the path tool?
Any three sides are mathematically correct

I would get used to using the Unified transform tool in path mode to scale / move / rotate the path.
Then to color in the triangle Select -> Path to Selection and fill with solid / pattern / gradient. Edit -> Stroke Path for an outline.
You might think is complicated compared with gfig but it easily editable and the path remains to re-use at a later date.
There are plugins to make path shapes, some simple, some complicated. I recommend, get used to the basics first.
