  The geometrical relationship between the distribution of circumstellar
matter, observed optical linear polarization, outflows and binary orbital plane
in Herbig Ae/Be stars is investigated. Optical linear polarization measurements
carried out for a number of Herbig Ae/Be stars that are either known to be in
binary systems and/or have bipolar jets are presented in this paper. Available
information on the position angles of polarization, outflows and binary
companions for Herbig Ae/Be stars is compiled and analysed for any possible
correlations. In $\approx 85%$ of the sources the outflow position angle is
within $30^{\circ}$ of being parallel or perpendicular to the polarization
position angle. In $\approx 81%$ of the sources the binary position angle is
within $30^{\circ}$ of being parallel or perpendicular to the polarization
position angle. Out of 15 sources with bipolar outflows, 10 sources have the
binary position angle within $30^{\circ}$ of being perpendicular to the outflow
position angle. These results favour those binary formation mechanisms in which
the binary components and the disks around individual stars or circumbinary
disks are coplanar.
