<p>Superconductivity in strongly correlated electron systems often exhibits broken rotational symmetry. However, transport anisotropy is typically already present in the metallic phase above the superconducting transition, raising the question of whether the rotation symmetry breaking in the superconducting state is intrinsic to the order parameter or inherited from an anisotropic normal state. Here we demonstrate that electronic nematicity—which is driven by Coulomb-mediated rotational symmetry breaking—serves as a crucial link to understanding the relationship between superconductivity and strange metallicity. We identify an angular interplay among nematicity, superconductivity and strange metallicity in magic-angle twisted trilayer graphene through angle-resolved transport measurement. Specifically, the preferred superconducting transport direction aligns with the principal axis of the metallic phase that exhibits the maximum resistivity, whereas the strange metal behaviour is locked to the principal axis of the metallic phase with the lowest resistivity. These results place strong constraints on the symmetry of the superconducting order parameter, revealing a pathway for probing the microscopic mechanisms that govern superconductivity in strongly interacting two-dimensional systems.</p>
