Abstract : We show that all mixing angles are determined, within experimental uncertainty, by a product of SU2 horizontal symmetries intimately linked to the algebra of weak neutral currents. This concerns: on one hand, the three quark mixing angles; on the other hand, a neutrino-like pattern in which theta {23} is maximal and tan 2 theta {12} = 2. The latter turns out to exactly satisfy the quark-lepton complementarity condition- theta c + theta {12} = pi-4. Moreover, among all solutions, two values for the third neutrino mixing angle arise, which satisfy the bound sin^2theta {13} \leq 0.1: theta {13} = +- 5.7 10^{-3} and theta {13} = +- 0.2717.
