A GENERALIZATION OF THE ORTHOCENTRIC TRIANGLE

The author proposes a generalization of the orthic triangle. The generalized triangle is defined by an arbitrary point of Ceva \(P\) and it is in perspective with the reference triangle \(A B C\). We call it the \(H\)-triangle of point \(P\). We call the...
