It has recently been speculated that the solar neutrino mixing angle is connected to the golden ratio φ. Two such proposals have been made, cot θ12=φ and cos θ12=φ/2. We compare these ansätze and discuss a model leading to cos θ12=φ/2 based on the dihedral group D10. This symmetry is a natural candidate because the angle in the expression cos θ12=φ/2 is simply π/5, or 36°. This is the exterior angle of a decagon and D10 is its rotational symmetry group. We also estimate radiative corrections to the golden ratio predictions.
