Oh a triangulator machine! Very cool! Right, there are four different types of triangle. First, here's an isosceles triangle, it has two equal length sides and two equal angles. Oh! Very clever!
Four of their proofs work for non-isosceles right triangles, while the fifth proof works for all right triangles. The first ...
