Triangle their internal angles, measured here in degrees. A triangle that has two angles with the same measure also has two sides with the same length, and therefore it is an isosceles triangle. It follows that in a triangle where all angles have the same measure, all three sides have the same length, and such a triangle is therefore equilateral. 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
Three Represents advanced culture, and the interests of the overwhelming majority. The formal statement of the theory is: One possible interpretation of the "Three Represents": One of the main goals of the Three Represents is to change the Communist Party of China into a governmental and more democratic party. This opens up the Party to "the overwhelming majority of the Chinese people", as well as businessmen and managers.
