A search is presented for physics beyond the standard model, based onmeasurements of dijet angular distributions in proton-proton collisions at$\sqrt{s}=$ 13 TeV. The data collected with the CMS detector at the LHCcorrespond to an integrated luminosity of 35.9 fb$^{-1}$. The observeddistributions are found to be in agreement with predictions from perturbativequantum chromodynamics that include electroweak corrections. Constraints areplaced on models containing quark contact interactions, extra spatialdimensions, quantum black holes, or dark matter using the detector-leveldistributions. In a benchmark model where only left-handed quarks participate,contact interactions are excluded at the 95% confidence level up to a scale of12.8 or 17.5 TeV, for destructive or constructive interference, respectively.The most stringent lower limits to date are set on the ultraviolet cutoff inthe Arkani-Hamed-Dimopoulos-Dvali model of extra dimensions. In theGiudice-Rattazzi-Wells convention, the cutoff scale is excluded up to 10.1 TeV.The production of quantum black holes is excluded for masses below 5.9 and 8.2TeV, depending on the model. For the first time, lower limits between 2.0 and4.6 TeV are set on the mass of a dark matter mediator for (axial-)vectormediators, for the universal quark coupling $g_\mathrm{q}\geq$ 1.
