  Angular distributions of charged particles relative to jet axes are studied
in $\sqrt{s_{\mathrm{NN}}}$ = 200 GeV Au+Au collisions as a function of the jet
orientation with respect to the event plane. This differential study tests the
expected path-length dependence of energy loss experienced by a hard-scattered
parton as it traverses the hot and dense medium formed in heavy-ion collisions.
A second-order event plane is used in the analysis as an experimental estimate
of the reaction plane formed by the collision impact parameter and the beam
direction. Charged-particle jets with $15 < p_{\rm T, jet} <$ 20 and $20 <
p_{\rm T, jet} <$ 40 GeV/$c$ were reconstructed with the anti-$k_{\rm T}$
algorithm with radius parameter setting of (R=0.4) in the 20-50\% centrality
bin to maximize the initial-state eccentricity of the interaction region. The
reaction plane fit method is implemented to remove the flow-modulated
background with better precision than prior methods. Yields and widths of
jet-associated charged-hadron distributions are extracted in three angular bins
between the jet axis and the event plane. The event-plane (EP) dependence is
further quantified by ratios of the associated yields in different EP bins. No
dependence on orientation of the jet axis with respect to the event plane is
seen within the uncertainties in the kinematic regime studied. This finding is
consistent with a similar experimental observation by ALICE in
$\sqrt{s_{\mathrm{NN}}}$ = 2.76 TeV Pb+Pb collision data.
