Transverse sphericity, a unique event shape variable, is employed to classify nucleus-nucleus collision events into isotropic and jetty categories. We present a systematic study on the transverse momentum spectra, particle yield and collective flow parameters of different charged hadrons for these two categories of Au+Au events, generated at GeV by a multi phase transport model in its string melting configuration. The transverse momentum spectra of charged hadrons obtained for the isotropic and jetty events themselves provide an indication of the onset of collective behavior. The elliptic flow parameter for the jetty events are found to be much higher in magnitude than those obtained from both the isotropic and entire class of events. However, no such dependence of the triangular flow parameter on transverse sphericity is noticed.
