Tarry Point
The point at which the lines through the Vertices of a Triangle Perpendicular tothe corresponding sides of the first Brocard Triangle, are Concurrent. The Tarry pointlies on the Circumcircle opposite the Steiner Point. It has Triangle CenterFunction
where
is the Brocard Angle. The Simson Line of the Tarry point is Perpendicular to the line 
, when 
is the Circumcenter and 
is the Lemoine Point.See also Brocard Angle, Brocard Triangles, Circumcircle, Lemoine Point, Simson Line,Steiner Points
