2. Relative to two distinct reference points.
   • 1878, F. Franklin, “Bipunctual Coordinates”, in American Journal of Mathematics, volume 1, page 156:

     The two systems are, in fact, practically identical; whatever can be proved for or with the one can be proved for or with the other; and it is only their relations to the bipunctual and bilinear systems that the distinction between the tripunctual and the trilinear systems comes into play: tripunctual coordinates standing in the same relation to bipunctual coordinates as trilinear to bilinear .

   • 1922, Henry Frederick Baker, Principles of geometry: Foundations - Volume 1, page 123:

     If X, Y, Z be a self-polar triad in regard to a conic, and O be any point, and XO, YO, and ZO meet YZ, ZX, XY, respectively, in A, B, C, then the conic is bipunctual in regard to A , B , C.

   • 1944, The Mathematics Student - Volumes 11-17, page 54:
