Showing triangulation of equilateral triangle is non-regular

WebJun 30, 2024 · I am trying to show that this triangulation is non-regular (sometimes called non-convex I think). By regular I mean there exists a convex function from the triangulation to $\mathbb{R}$ such that the faces of the lower convex hull of the lifted points correspond to the triangles of the triangulation. Another definition I have seen is that the domains of … WebThere are five regular polyhedrons. The following is the list of five regular polyhedrons.
