mesh – Is there a way to automatically use triangular elements in ToElementMesh

I have a simple code to generate a mesh on a rectangle.

(* Generic Clear All *)
Erase everything["Global`*"];

(* Import Mathematica Finite Element Model Library *)
Needs["NDSolve`FEM`"];

(* Generate an element mesh for a 13 [m] [Times] 6 [m] Region *)
ToElementMesh[Rectangle[{-6.5,0},{6.5,6}]]["Wireframe"]

When I run this code, it generates a mesh with rectangular elements. I would like the mesh generator to use triangular elements. It seems that I can expose it manually and use the option "MeshElements". This would require me to enter a list of individual coordinates for each triangular element.

Is there a way to automatically generate a grid with triangular elements instead of rectangular elements?
