The Nagel Point
The Nagel Point
A circle drawn outside a triangle that is tangent to the extensions of two of its sides and to the third side is an excircle.
The lines connecting the vertices of a triangle with the corresponding points of tangency of the three excircles are concurrent. The intersection is called the Nagel point.
