Book excerpt: The primary objective of the BABAR Experiment is to test the Standard Model explanation of CP violation in weak decays by over-constraining the CKM Unitarity Triangle. This includes the measurement of all three angles of the triangle. Although precise measurements of the angle [beta] have been obtained using B decays to charmonium states, the remaining angles, [alpha] and [gamma], pose greater experimental challenges. In this paper, the latest measurements of modes which will constrain [alpha] and [gamma] will be presented, including B[sup 0] --> [rho][sup +][rho][sup -] for [alpha] and a measurement of sin(2[beta] + [gamma]) from the B[sup 0] --> D(*)[sup [+-]][pi][sup [-+]] system.
