Default geometry question?

if i have a circle,and i have N lines that goes from one point to another.what is the maximum pices inside the circle?(i know that if i have 10 lines,the maximum will be 56)*i knew that it's 56 because it's 2+3...+10,i just don't know whyto stiffmeister:not correct because you can have pices that don't have points a the circule56 is correct but i don't know whyto spirit dummy:if n=10,the result is an un natural number
