The results reveal distinct anisotropies in both the longitudinal and planar Hall resistances as the magnetic field is rotated within the plane, which are well-captured by the planar Hall effect(PHE) model. Further analysis indicates that the primary contribution to the PHE in GaGeTe arises from its ferromagnetic component and anisotropic orbital resistance, rather than topologically nontrivial chiral anomaly.
