The magnetic susceptibility and the magnetization as a function of magnetic field are calculated exactly for the antiferromagnetic Ising and Heisenberg models of a triangle cluster. Both characters of the bending of the inverse susceptibility as a function of temperature and the 1/3 plateau of magnetization found in the Monte Carlo simulation study for the triangle based lattice systems survive even in a single triangle cluster. The quantum effect and the spin magnitude are discussed concerning the characters.
