Sorry to dissapoint guys, but the method doesn't work... If you been getting good results with it it has been because of sheer luck (inner angles of most triangles tend to be very similar for the most part)
This is in no way intended as a criticism to the method, since the principle presented in it is sound, except that there is one dislexic error in the explanation that causes the incorrect results.
EDITED BY AUTHOR!!
My God, that explanation was awfull, the guy on the next post is correct in not liking how it was
I corrected it and have now created a new thread. Please visit it, I think you'll find it VERY USEFULL
