Butterfly theorem

The beautiful butterfly theorem (Théorème du papillon) is a classical result in Euclidean geometry. It has several proofs. According to Coxeter and Greitzer, Geometry Revisited 1967, one of the solver was W. G. Horner whose name is associated with Horner’s Method of approximating zeros of polynomials.
