What is the center of gravity of the perimeter of a triangle (as when a piece of wire is bent into triangular form)?

Consider vertices (-.01,0), (.01,0), (0,6). The centroid formula gives (0,2), but the small base has hardly any weight, and the CG should be quite near (0,3), near the middle of the long sides.
