WebAug 25, 2015 · A convex polygon is one where all interior angle measurements are less than 180 degrees, and the hexagon means 6 sides. To get diagonals, you draw a line to connect an angle to another angle (never to sides), and count up how many different lines you get. In this case, you can draw 9. You can also use this formula (n (n-3))/2 where n= number of ... WebApr 7, 2024 · The formula for calculating the number of diagonals in an octagon is: n (n-3)/2. Where n is the number of sides of the polygon. In this case, n is equal to 8, so the formula becomes: 8 (8-3)/2. This simplifies to: 20. Therefore, there are 20 diagonals in an octagon.
