The quantum geometry has significant consequences in determining transportand optical properties in quantum materials. Here, we use a semiclassicalformalism coupled with perturbative corrections unifying the nonlinearanomalous Hall effect (NLAHE) and nonreciprocal magnetoresistance (NMR,longitudinal resistance) from the quantum geometry. In the dc limit, bothtransverse and longitudinal nonlinear conductivities include a term due to thenormalized quantum metric dipole. The quantum metric contribution is intrinsicand does not scale with the quasiparticle lifetime. We demonstrate thecoexistence of a NLAHE and NMR in films of the doped antiferromagentictopological insulator MnBi$_2$Te$_4$. Our work indicates that both longitudinaland transverse nonlinear transport provide a sensitive probe of the quantumgeometry in solids.
