how many internal diagonals does a nonagon ( nine sided polygon ) have ?
"number of diagonals in any polygon can be found using this formula : n ( n - 3 ) / 2 here n = 9 no . of diagonals = 9 ( 9 - 3 ) / 2 = 27 ans b"
multiply(subtract(multiply(const_2, const_4), const_3), divide(multiply(const_2, const_4), const_2))
