Step-by-step explanation:

Difference between the number of diagonals in an octagon and hexagon?​

Number of Diagonals in a polygon = n(n-3)/2

where n = sides of polygon

octagon has 8 sides

=> number of diagonals in octagon = 8(8-3)/2 = 20

Hexagon has 8 sides

=> number of diagonals in Hexagon = 6(6-3)/2 = 9

Difference between the number of diagonals in an octagon and hexagon = 20 - 9 = 11
