WebSep 27, 2024 · A polygon with 19 sides, for example, has 152 diagonals. That would be a bit difficult to count. This is where a nice, useful, and simple formula comes in to help. WebA six sided polygon has 0 + 2 + 3 + 4 = 9 diagonals and continuing this we would see that A seven sided polygon will have 0 + 2 + 3 + 4 + 5 = 14 diagonals. Hence an n sided polygon will have 2 + 3 + 4 + 5 + … + (n – 2) diagonals. Formula – Notice that Figure 1 has 4 vertices, and each vertex connects to one diagonal.

WebFeb 1, 2024 · Question 1: How many diagonals do a hexagon has, find using the diagonal of a polygon formula. Solution: Hexagon is a polygon that is formed by six straight lines. So a hexagon has 6 sides so n = 6. Using formula, diagonals = (n × (n – 3))/2 . Put n = 6. Diagonals = (6 × (6 – 3))/2 = 9. Hence a hexagon has nine diagonals.
