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

Any three sides are mathematically correct    but for say an isosceles triangle.  Bring up the grid from the view menu and make a triangle using the grid and the paths tool. To join the start and end points hold the ctrl key (look for a double circle icon) and click on the first point. Turn the grid off from view menu.

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.
