Angular distributions of radiative quarkonium cascade decays into three particles are presented, using the helicity formalism. These three particles can be either three pseudoscalar mesons or a lepton-antilepton pair and a pseudoscalar meson. Three-meson final states also occur in two-body sequential decays when the intermediate state {chi} formed in the radiative decay of quarkonium subsequently decays into a meson resonance decaying into a meson pair, along with a third meson. Inferences on the spins and parities of the intermediate {chi} are made.
