How many diagonals does a hexagon have?
(a) 9
(b) 8
(c) 2
(d) 6

Solution:

We have to find the number of diagonals of a hexagon.

A hexagon is defined as a closed 2D shape that is made up of six straight lines.

It is a two-dimensional shape with six sides, six vertices, and six interior angles.

We know that the number of diagonals in a polygon of n sides = n(n-3)/2

Here, n = 6

Number of diagonals = 6(6-3)/2

= 6(3)/2

= 3(3)

= 9

Therefore, the number of diagonals is 9.
