Hello, Alexandr!
Being highly impressed by the variety of puzzles at your site (I saved it in my bookmarks and intend to educate myself when my boss doesn't see me), I dare to ask you, if it is not a trouble. Is there any simple and beautiful theorem, that will allow me quickly prove whether a point lies within triangle or outside its boundaries. I have a feeling that something like this must exist. I am asking in one hope only that a person like you will probably know it at once.
Sincerely, Irina.
