how many internal diagonals does a heptagon ( seven sided polygon ) have ?
"number of diagonals in any polygon can be found using this formula : n ( n - 3 ) / 2 here n = 7 no . of diagonals = 7 ( 7 - 3 ) / 2 = 14 ans c"
multiply(subtract(multiply(const_2, const_4), const_3), divide(multiply(const_2, const_4), const_2))
