Bevan point

The Bevan point, named after Benjamin Bevan, is a triangle center. It is defined as center of the Bevan circle, that is the circle through the centers of the three excircles of a triangle.

The Bevan point M of triangle ABC has the same distance from its Euler line e as its incenter I and the circumcenter O is the midpoint of the line segment MI. The length of MI is given by

where R denotes the radius of the circumcircle and a, b and c the sides of the triangle ABC. The Bevan is point is also the midpoint of the line segment NL connecting the Nagel point N and the Longchamps point L. The radius of the Bevan circle is 2R, that is twice the radius of the circumcircle.
