Meshes are a very simple kind of 3D objects, used for example by Sketchup, Blender or 3D studio Max. They are composed of 3 elements: points (also called vertices), lines (also called edges) and faces. In many applications, FreeCAD included, faces can have only 3 vertices. But of course nothing prevents you from having a bigger plane face made of several coplanar triangles.
