The most basic figures in geometry are undefined terms, which cannot be defined by using other figures. The undefined terms point, line, and plane are the building blocks of geometry. Points that lie on the same line are collinear. K, L, and M are collinear. K, L, and N are noncollinear. Points that lie on the same plane are coplanar.

to di eomorphisms and the subject of di erential geometry is to study spaces up to isometries. Thus in di erential geometry our spaces are equipped with an additional structure, a (Riemannian) metric, and some important concepts we encounter are distance, geodesics, the Levi-Civita connection, and curvature.
