  In this work, the postulation that weak CP phase originates in a certain
geometry, is further discussed. According to this postulation, the weak CP
phase is determined by three mixing angles. So, if we can determine
experimentally three elements of the Cabibbo-Kobayashi-Maskawa matrix, we can
then determine the whole CKM matrix and correspondingly, the unitarity
triangle. We find that the angle gamma is about pi/2 and the weak CP phase
delta (delta_{13}) only can exist in the first or fourth quadrant. The
conclusions coincide with the relevant analysis. Some other predictions are
given in this paper, the comparison of the predictions based on the postulation
to the relevant experimental and theoretical results is listed. All the
predictions are consistent with the present experimental results.
