How many diagnals are in a 14-gon?

Answer 1

To calculate the number of diagonals in a polygon, you can use the formula: ( \frac{n(n-3)}{2} ), where ( n ) is the number of sides. For a 14-gon, substituting ( n = 14 ) gives: ( \frac{14(14-3)}{2} = \frac{14 \times 11}{2} = 77 ). Therefore, a 14-gon has 77 diagonals.
