We present recent measurements of the CKM angles alpha and gamma using data collected by the BaBar detector at the PEP-II asymmetric-energy e{sup +}e{sup -} collider at the Stanford Linear Accelerator Center. In addition to constraints on alpha from the decays B0 {yields} {pi}{sup +}{pi}{sup -}, B0 {yields} {rho}{sup +} {pi}{sup -} and B0 {yields} {rho}{sup +}{rho}{sup -}, we also report the first measurement of time-dependent CP asymmetries in the decay B0 {yields} a1{sup +}(1260) {pi}{sup -}. We present measurements of gamma in B+ {yields} D(*)0 K+ decays using a Dalitz analysis in the modes D{sup 0} {yields} Ks {pi}{sup +}{pi}{sup -} and D{sup 0} {yields} {pi}{sup +}{pi}{sup -}{pi}{sup 0}.
