An exmedian is a parallel to a side of a triangle through the opposite vertex. So in the above diagram, is the exmedian of side , and so on. The pairwise intersections of the exmedians are called exmedian points, and the triangle determined by the exmedian points is called the anticomplementary triangle of .
