When lines have more than 2 points on it, they are defined by the 2 points with lowest serial number.

These QL-lines are described further with their properties:

  • QL-L1: P5, P7, P12, P20, P22, P23 (Newton Line)
  • QL-L2: P2, P7, P9 (Steiner Line)
  • QL-L3: P19 (QL-Pedal Line)
  • QL-L4: P2, P3 (Morley Line)
  • QL-L5: P1, P7, P19 (NSM-Line)
  • QL-L6: P2, P10 (Quasi Ortholine)
  • QL-L7: P8, P9, P10, P11 (QL-DT-Euler Line)
  • QL-L8: P8, P12, P14, P15, P18 (QL-Centroids Line)
  • QL-L9: P18, P23 (M3D Line)

Other QL-Lines without name but with at least 3 Points on it are:

  • P1, P8, P24
