Remove N-gons

This command converts the selected objects’ n-gons to triangles and quadrangles.

While you are modeling you can check up how the n-gons would be triangulated by enabling the N-gon Lines option in the viewport settings on the Filter tab (viewport: Edit / Configure). Keep in mind that these triangulation lines may change at any time while you are editing the mesh.
