Summary
DescriptionMorley.png
English: This figure shows the 18 Morley triangles of a given triangle ABC. All six trisectors at each of the given triangle's three angles are drawn and color-coded such the intersections of trisectors with the same color identify 27 points that lie on 9 lines, each line containing 6 of the intersection points, and each pair of lines being either parallel or intersecting at an angle of 60 degrees. See Morley's_trisector_theorem.
