The CKM paradigm has been proven to be successful in explaining the flavour structure of the standard model and the non-trivial imaginary phase of the CKM matrix is the only know source of CP-violation. B-meson decays allow us to precisely determine the fundamental parameters of the CKM matrix and put stringent constraints on the models of New Physics. I present some of the most recent measurements related to the CKM Unitarity Triangle performed by the BaBar experiment, located at the SLAC National Accelerator Laboratory. Most results are based on the final BaBar dataset, consisting of 467 M BB pairs. Show Partial Abstract
