Points of the Escutcheon
There are nine points distinguished in heraldry by the first nine letters of the alphabet- three at top, A, B, C; three down the middle, D, E, F; and three at the bottom, G, H, I. The first three are chiefs; the middle three are the collar point, fess point, and nombril or navel point; the bottom three are the base points.
