Abstract
In this paper we study the interior angle sums of geodesic triangles in $$\mathbf {Nil}$$ Nil geometry and prove that these can be larger, equal or less than $$\pi $$ π . We use for the computations the projective model of $$\mathbf {Nil}$$ Nil introduced by Molnár (Beitr. Algebra Geom. 38(2):261–288, 1997).
