There are many proofs of Morley's theorem, some of which are very technical.[1] Several early proofs were based on delicate trigonometric calculations. The first published geometric proof was given by M. T. Naraniengar in 1909.[2] Recent proofs include an algebraic proof by Alain Connes (1988, 2004) extending the theorem to general fields, and John Conway's elementary geometry proof.[3][4] The latter starts with an equilateral triangle and shows that a triangle may be built around it which will be similar to any selected triangle. Morley's theorem does not hold in spherical[5] and hyperbolic geometry.
