Formula for diagonals of a polygon

WebThe diagonal of a polygon formula is used to calculate the number of diagonals of a polygon. It says The number of diagonals of a polygon = n (n−3)/2 Here 'n' is the number of sides polygon has. Let us see the applications of the diagonal of a polygon formula in the following section. Solved Examples Using Diagonal of a Polygon Formula WebOct 29, 2012 · This formula is most easily proved by using complex numbers, for then we are just dealing with the sum of two geometric progressions. In that formula, let φ = 0, and use n − 1 instead of n. Note that the already quite simple formula simplifies further. Now repeat this calculation at all n vertices. We get the same number each time.
