Orthopoles, Flanks, and Vecten Points

Abstract

Erect a square outwardly (or inwardly) from each side of the triangle. For the flank lines construct orthopoles. The lines from this orthopoles to corre- sponding vertexes of triangle concur in the Vecten point (or in the Inner Vecten point).

This fact is showing together with a number of other interesting results, which include complex coordinates of Vecten points and orthopole.
