The Brocard Triangle
- Steve Phelps
From each vertex are two cevians, one through each Brocard point. Consider the cevians from A. They contain B_1 and and B_2. Notice each cevian crosses another cevian from another vertex. These intersection points form the first Brocard Triangle. The Circumcircle of this triangle is the FIrst Brocard Circle and contains the Circumcenter.
