WebThe formula that is used to find the number of diagonals in any polygon is, Number of diagonals = n (n-3)/2; where 'n' represents the number of sides of the polygon. In this case, there are 8 sides in an octagon. After substituting the value of 'n' = 8 in the formula, we get, Number of diagonals = n (n-3)/2 = 8 (8 - 3)/2 = (8 × 5)/2 = 20. WebAnswer (1 of 4): (n)(n-3)/2 where n is the number of vertices. A square has (4)(1)/2 = 2 diagonals; a pentagon has (5)(2)/2 = 5 diagonals; a hexagon has (6)(3)/2 = 9 diagonals; a heptagon has (7)(4)/2 = 14 diagonals; and so on. Basically you can draw a diagonal from any point to any of (n-3) p...
