Brocard Axis
The Line 
passing through the Lemoine Point 
and Circumcenter
of a Triangle. The distance 
is called the Brocard Diameter. The Brocard axis isPerpendicular to the Lemoine Axis and is the Isogonal Conjugate of Kiepert's Hyperbola. It hasequations
The Lemoine Point, Circumcenter, Isodynamic Points, and Brocard Midpoint all lie along the Brocardaxis. Note that the Brocard axis is not equivalent to the Brocard Line.See also Brocard Circle, Brocard Diameter, Brocard Line
