how many internal diagonals does a octagon ( eight sided polygon ) have ?
number of diagonals in any polygon can be found using this formula : n ( n - 3 ) / 2 here n = 8 no . of diagonals = 8 ( 8 - 3 ) / 2 = 20 ans e
multiply(subtract(multiply(const_2, const_4), const_3), divide(multiply(const_2, const_4), const_2))
