I would like to know if there are any method to divide a circle (a pizza) in three equal area parts (supposing you are able to divide it in two perfectly)
The practical aproach is to cut it aproximated in 3,
and to minimize error by sub-dividing every part in two, in as many portion as possible.
so when I get 16 bad cutted (instead of 15) the error is small
but diners complain about size ;)
