Highly energetic jets produced in nuclear collisions are considered to be a direct probe of hot and dense medium created in the collision. The jet measurements both at LHC and RHIC indicate a presence of "jet quenching" - strong energy loss of fast partons in the hot and dense QCD medium. This talk presents study of properties of the multi-jet production in heavy ion collisions presented in terms of jet angular correlations. The jet angular correlations are valuable tool to study the beyond leading order effects in QCD and are expected to shade a new light on the process of the energy loss. The analysis is performed using Pb+Pb data collected in 2011 by the ATLAS detector at the center of mass energy of 2.76 TeV.
