In this paper, during the 1-parameter closed planar homothetic motions, the polar moments of inertia for the orbit curves are expressed in the complex plane and the Holditch type theorem for polar moments of inertia is given. In the case of the homothetic scale h ≡ 1 the results given by [3] are obtained as a special case.
