GIMP

there is a task to draw a tetrahedron in gimp, but in gfig there is no necessary figure.

The tetrahedron should turn out mathematically even and be correct.

Answer 1

in 2D, you can only draw a projection of a 3D body.
What is "mathematical plane projection"? Any projection of a tetrahedron onto a plane will be either a triangle or a quadrilateral. In a particular case, it will be an equilateral triangle (one of the faces of a tetrahedron). If you need some specific projection, then you need to write about it in the question.
