To make four triangles, we should go into 3D.
Three triangles in space and one triangle in base

In fact it gives eight equilateral triangles if you count the two big ones.

If you move one of masters big triangles down so that a vertex falls on the side of the other you end up with exactly six equilateral triangles (including the two big ones).
