  We give an overview of the polarization in the broad lines of Active Galactic
Nuclei (AGNs), where we can use the polarization angle for determination of the
black hole masses (as given in [1]). Especially, we considered nine AGNs with
strong optical Fe II lines in the spectra, where five of them are typical
Narrow Line Sy1 (NLSy1) and four Broad Line Sy1 (BLSy1) AGNs . Comparing the
polarization parameters and black hole masses (obtained from polarization) we
confirmed that NLSy1 have smaller black hole masses than BLSy1, and seem to
have more compact Broad Line Region (BLR) and smaller inner torus radius than
BLSy1
