@Fil Albuquerque,
From BS to BS, quite a talent.
I have demonstrated how to multiply and divide a line by a line in geometry, never before demonstrated, perhaps you can now try the four basic moves in arithmetic with the language called geometry. You can find that on the archive also.
I was just too stupid to let all the BS go on forever, so I did the demonstration.
The figure is a reality, not a worthless theory. And, if you should ever master that one, try the Delian Quest. I did solve the Delian Problem. Not a theory either.
With enough study of geometry, you may learn the difference between a boundary, the material in a boudary, and the two together as a thing. Until you do, I have to agree with Plato and Aristotle, your not worth conversing with. When you have mastered it, you will know how names can and cannot be manipulated.
