Query: A Note on CP Invariance and Rephasing Invariance   CP invariance condition and rephasing invariance in KM scheme of CP violation
is discussed. The CP violation measures in B physics, corresponding to the
three angles of unitarity triangle are given in rephasing invariant form. With
the obtained results it is shown that the sum of the three CP angles to be
measured at B factories becomes $\pi$ even if the Kobayashi-Maskwa matrix is
not a $3\times 3$ unitary matrix under reasonable assumptions.
