We investigated the sample of galaxies belonging to the Tully groups of galaxies. We analyzed the orientation of galaxies inside the group. We did not found significant deviation from isotropy both in orientation of position angles and angles $\delta_D$ and $\eta$ giving the spatial orientation of galaxy planes. Moreover we analyzed consequences of different approximation of "true shape" of galaxies and showed possible influence of this problem for investigation of spatial orientation of galaxies. Implications of the obtained results for theory of galaxy formation was discussed as well.
