Tarry point



In geometry, the Tarry point $T$ for a triangle $△ABC$ is a point of concurrency of the lines through the vertices of the triangle perpendicular to the corresponding sides of the triangle's first Brocard triangle $△DEF$. The Tarry point lies on the other endpoint of the diameter of the circumcircle drawn through the Steiner point. The point is named for Gaston Tarry.
