One of the many exciting arenas of physics currently under study at RHIC is the attempt to understand and quantify the phenomenon of jet quenching observed in central collisions of relativistic heavy-ion collisions. Measurements of the azimuthal anisotropy of high-$\pT$
neutral pion ($\pi^0$) production in \mbox{Au+Au} collisions at $\sqrt{s}_{NN} = 200$~GeV by the PHENIX experiment can be used to gain insight into the mechanisms at work during the interaction of the medium created in such collisions[1] and will be presented. The amplitude of the second Fourier component ($v_2$) as well as the
nuclear modification factor with respect to the reaction plane ($R_{AA}(\Delta\phi)$) will be discussed in the context of the light they shed on the energy lost by fast partons as they traverse the medium. A jet-quenching motivated geometric analysis will be presented that attempts to simultaneously describe the centrality dependence and reaction plane angle dependence of the \piz suppression in terms of the path lengths of hypothetical parent partons in the medium.
