Abstract
We present a summary of measurements sensitive to the CKM angles \phi_1 and \phi_2, performed by the Belle experiment using the final data sample of 772 \times 10^{6} pairs at the \Upsilon(4S) resonance produced at the KEK asymmetric e^+e^- collider. We discuss CP asymmetries from the decays , which are sensitive to \phi_1 and from , being sensitive to \phi_2. Furthermore the measurement of the branching fraction of decays and fraction of longitudinal polarization in this decay is presented and used to constrain \phi_2 with an isospin analysis in the system.
