Web18 jun. 2014 · Suppose you know a polygon has, say, 104 diagonals. Can this formula be used to find the number of sides? Yes! Substituting 104 for d leads to this: 104 = (n)(n … Web4 sides=1 intersect (center, diagonals form an 'X' ) 5 sides=5 intersects (diagonals form a star) 6 sides=13 intersects And so on. Chris The answer to your question is easy when the polygon has an odd number of sides, but quite complicated when the number is even! It is VERY difficult to see why this is so.

WebDiagonals: A nonagon has 27 diagonals, which are lines that connect non-adjacent vertices of the polygon. The formula to calculate the number of diagonals in a nonagon is n (n-3)/2, where n is the number of sides. Symmetry: A nonagon has nine lines of symmetry, which divide the polygon into nine congruent parts.

Web7 nov. 2014 · So we need to find the numbers of diagonals which pass through the centre. Note further that we just need to find one point, and find another point which is symmetry … WebDiagonals for polygons of all shapes and sizes can be made and for every shape; there is a formula to determine the number of diagonals.
