The Clawson Point
The Clawson point is the homothetic center of the orthic triangle A'B'C' and the extangents triangle A''B''C''. In the figure, the reference triangle is labeled ABC. Its orthic triangle, A'B'C', is formed by the feet of the altitudes of triangle ABC - for example, A' is the point in which the altitude through A meets side BC. The extangents triangle, labeled A"B"C", is formed by the lines externally tangent to the excircles of triangle ABC. The lines A'A", B'B", C'C" concur in the Clawson point of triangle ABC. Only points A, B, and C are draggable.
