The values of sin2[alpha] and sin2[beta], where [alpha] and [beta] are angles of the unitarity triangle, will be readily measured in a [ital B] factory (and maybe also in hadron colliders). We study the standard model constraints in the sin2[alpha]-sin2[beta] plane. We use the results from recent analyses of [ital f][sub [ital B]] and [tau][sub [ital b]][vert bar][ital V][sub [ital c][ital b]][vert bar][sup 2] which take into account heavy-quark symmetry considerations. We find sin2[beta][ge]0.15 and most likely sin2[beta][approx gt]0.6, and emphasize the strong correlations between sin2[alpha] and sin2[beta]. Various schemes for quark mass matrices allow much smaller areas in the sin2[alpha]-sin2[beta] plane. We study the schemes of Fritzsch, of Dimopoulos, Hall, and Raby, and of Giudice, as well as the symmetric Cabibbo-Kobayashi-Maskawa'' idea, and show how [ital CP] asymmetries in [ital B] decays will crucially test each of these schemes.
