Measurements of the modes B {yields} {pi}{pi} and B {yields} {rho}{rho} and their implications on the angle a of the CKM unitarity triangle are presented. Results of the Dalitz analysis of the modes B {yields} D(*)0K(*) and the derived constraints on the angle {gamma} are then shown. These measurements are based on a sample of approximately 230.106 B pairs taken at the {upsilon}(4S) resonance collected by the BABAR detector at the PEP-II asymmetric-energy beam factory at SLAC.
