The idea of a proof is to make a universal statement – for example, you don’t just want to say that the angles in some triangles add up to 180\degree, you want to say that the angles in all triangles add up to 180\degree.This is a proof you actually do have to know, and you can see it here ( interior and exterior angles revision ).
