The triangle OAOBOC of circumcenters of the flanks is perspective with ABC at the symmedian point K of ABC. In particular, the A-Cevian of K in ABC (the line AK) is the same line as the A-Cevian of OA in the A-flank. Since ABC is the A-flank of triangle ABaCa, the A-Cevian of KA in the A-flank is the same line as the A-Cevian of O in ABC as well. Clearly, the same statement can be made for the B- and C-flanks. The triangle KAKBKC of symmedian points of the flanks is perspective with ABC at the circumcenter O. For this relation we call the triangle centers O and K friends. See Figure 3. More generally, we say that P befriends Q if the triangle PAPBPC is perspective with ABC at Q. Such a friendship relation is always symmetric since, as we have remarked earlier, ABC is the A-, B-, C-flank respectively of its A-, B-, C-flanks
