Isospin relations are used to eliminate hadronic uncertainties in various CP asymmetries in B 0 decays. In addition to the simple triangle relations for the ππ mode, we study quadrilateral relations for Kπ and pentagon relations for ρπ. A combined angular and isospin analysis is required for ρρ. These methods are useful also for three-body decays such as Kππ. The magnitude of the penguin amplitude can be extracted in various modes. The theoretical principles behind this analysis can be experimentally tested through sum rules for decay rates prior to the measurement of CP asymmetries
