    Equilateral chordal triangles - Floor van Lamoen​

    When a circle intersects each of the sidelines of a triangle in two points, we can pair the intersections in such a way that three chords not along the sidelines bound a triangle, which we call a chordal triangle. In this paper we show that equilateral chordal triangles are homothetic to Morley's triangle, and identify all cases.
