- I am looking for a classic style proof to the following:
-
- The plumb lines of a plane triangle meet in a single point. Plumb line is
- the line dropped orthagonally from a vertex to the opposite side.
-
- The algebraic proof in analytical fashion is trivial, but I can't for the
- life of me get a classic Greek style proof. If you can help please e-mail.
-
- Much thanx.
