We report recent measurements of the three CKM angles of the Unitarity Triangle using about 383 millions [Formula: see text] pairs collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC.

We present results on time-dependent CP asymmetries in [Formula: see text] and B0 → K+K-K0. The measurements use a data sample consisting of approximately [Formula: see text] and 227(B0 → K+K-K0) million B-meson pairs recorded at the ϒ(4S) resonance with the BABAR detector at the PEP-II B-meson Factory at SLAC. From a time-dependent maximum likelihood fit, we measure for [Formula: see text]: the mixing-induced CP violation parameter [Formula: see text] and the direct CP violation parameter Cf0K = -0.24 ± 0.31 ( stat ) ± 0.15 ( syst ). From a simultaneous fit to [Formula: see text] and [Formula: see text] decays, we find: [Formula: see text] and CϕK = 0.00 ± 0.23 ( stat ) ± 0.05 ( syst ). For [Formula: see text] decays with [Formula: see text] decays excluded, we find: [Formula: see text] and [Formula: see text]. From the [Formula: see text] decays with [Formula: see text] decays excluded, we extract the fraction of CP-even final states from angular moments feven = 0.89 ± 0.08 ± 0.06.

We present preliminary measurements of branching fractions and direct CP violating asymmetries in charmless twobody B decays, obtained with the BABAR detector using a sample of 227 M [Formula: see text] decays. We report the first observation of [Formula: see text] and the first observation of direct CP violation in B0 → K+π- decays.

We report on recent measurements of branching fractions and CP violation observables of selected charmless hadronic B decays obtained from data collected with the BABAR detector at the PEP-II asymmetric-energy collider, operating at the ϒ(4S) resonance.
