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
