The orthic triangle is closely related to the tangential triangle, constructed as follows: let LA be the line tangent to the circumcircle of triangle ABC at vertex A, and define LB and LC analogously. Let A" = LB ∩ LC, B" = LC ∩ LA, C" = LC ∩ LA. The tangential triangle is A"B"C", whose sides are the tangents to triangle ABC's circumcircle at its vertices; it is homothetic to the orthic triangle.
