Charged-particle jet yields have been measured in semicentral Pb$-$Pbcollisions at center-of-mass energy per nucleon-nucleon collision $\sqrt{s_{\rmNN}} = 5$ TeV with the ALICE detector at the LHC. These yields are reported asa function of the jet transverse momentum, and further classified by theirangle with respect to the event plane and the event shape, characterized byellipticity, in an effort to study the path-length dependence of jet quenching.Jets were reconstructed at midrapidity from charged-particle tracks using theanti-$k_{\rm T}$ algorithm with resolution parameters $R =$ 0.2 and 0.4, withevent-plane angle and event-shape values determined using information fromforward scintillating detectors. The results presented in this letter showthat, in semicentral Pb$-$Pb collisions, there is no significant differencebetween jet yields in predominantly isotropic and elliptical events. However,out-of-plane jets are observed to be more suppressed than in-plane jets.Further, this relative suppression is greater for low transverse momentum ($<$50 GeV/$c$) $R =$ 0.2 jets produced in elliptical events, with out-of-plane toin-plane jet-yield ratios varying up to 5.2$\sigma$ between differentevent-shape classes. These results agree with previous studies indicating thatjets experience azimuthally anisotropic suppression when traversing the QGPmedium, and can provide additional constraints on the path-length dependence ofjet energy loss.
