In a hexagon no of diagonal equals no of ways we can choose two points(6C2) - Number of sides of hexagon(6) ; as we choose two adjacent points and we join them then we do not form a diagonal instead we form the side of the hexagon.
solution =6(C)2 - 6 = 6!/(4!×2!) - 6
= 15 - 6=9
•°•answer is there are 9 diagonals in a hexagon.
here ! stands for factorial
and C stands for number of combinations.
These might help you to find diagonal of a n sided regular closed figure which equals [n(C)2 - 2]

its too big (:
Step-by-step explanation:
this question is belongs to combination of numbers.
with the help of given formula,for hexagonal has 6 sides.
(Nc2 - 6)
6c2 - 6
15-6
9.
