GEOS circle
INTERSECTION OF FOUR LINES THAT ARE ASSOCIATED WITH A GENERALIZED TRIANGLE: THE EULER LINE, THE SODDY LINE, THE ORTHIC AXIS AND THE GERGONNE LINE
GEOS Circle; Geos circle
In geometry, the GEOS circle is derived from the intersection of four lines that are associated with a generalized triangle: the Euler line, the Soddy line, the orthic axis and the Gergonne line. Note that the Euler line is orthogonal to the orthic axis and that the Soddy line is orthogonal to the Gergonne line.
