Triangles are assumed to be two-dimensional plane figures, unless the context provides otherwise (see § Non-planar triangles, below). In rigorous treatments, a triangle is therefore called a 2-simplex (see also Polytope). Elementary facts about triangles were presented by Euclid, in books 1–4 of his Elements, written around 300 BC. http://www.se16.info/hgb/triangle.htm
