WebNumber of diagonals in any n sided polygon is = Total Number of Lines connected two points − Total number of sides of polygon. So we have n points so total number of lines is = nC 2, because we have to choose two points from n points. Total number of sides = n So Number of diagonals = 2n(n−1)−n Number of diagonals = 2n(n−3) WebMar 26, 2016 · You know what the formula for the number of diagonals in a polygon is, and you know that the polygon has 90 diagonals, so plug 90 in for the answer and solve for n: Thus, n equals 15 or –12. But because a polygon can’t have a negative number of sides, n must be 15. So you have a 15-sided polygon (a pentadecagon, in case you’re curious). irvin artistWebExamples: a square (or any quadrilateral) has 4 (4−3)/2 = 4×1/2 = 2 diagonals. an octagon has 8 (8−3)/2 = 8×5/2 = 20 diagonals. a triangle has 3 (3−3)/2 = 3×0/2 = 0 diagonals. irvin athearn
