Moise's theorem

Moise's Theorem, named after the mathematician Edwin Moise, is a result in the field of topology, specifically dealing with the characterization of certain types of surfaces. The theorem states that any triangle in Euclidean space can be decomposed into a finite number of pieces that can then be rearranged to form any other triangle, under a particular condition. In a more general sense, it also relates to the idea of "triangulation" of surfaces.
