OK, so the goal is not (or not only) drawing, but rather ....??

Do you need a function of some kind which also gives you any point on the sides of the triangle, not just the vertices? Or is Luc's approach already doing what you have in mind?

Oh! yes nice,

but my version considers the height of the triangle, changing which, for example, I get an isosceles triangle. however, the use of other geometric figures to build the triangle is not welcome.

The general case, for an n-angle and orientation o, is:

    Not sure what exactly you are looking for.

    If your goal is to just draw an equilateral triangle dependent on the side length and in the same position in the coordinate system as yours, a simple way would be this:

    As Luc wrote, three points are all you need - actually four as you have to duplicate the first one to get a closed figure. You can leave it to Mathcad's 2D plot to connect the points.

    Just read your answer to Luc's post where you say that you also want to draw isosceles triangles depending on the base length and the height.

    Here it is:
