  We calculated the polarization degree of hydrogen Balmer broad emission lines
from a number of active galactic nuclei (AGNs) with determined virial factors.
The objects were selected from the sample presented by Decarli et al.(2008). In
our calculations, we used the model of the flattened disc-like structure of the
broad-line emission region (BLR). In this model, the expression for the virial
factor makes it possible to determine the inclination angle for the flattened
BLR, which in turn yields the polarization degree of the broad emission lines.
As a result, we obtained the direct relation between the polarization degree
and the virial factor. We also compared the determined values of the
polarization degree with those obtained in polarimetric observations.
