Correct option is

A

9

A diagonal connects two non-consecutive vertices of a polygon

A hexagon has six sides.

There are 3 diagonals from a single vertex, and there are 6 vertices on a hexagon, which suggests there would be 18 diagonals in a hexagon.

However, we must divide by two as half of the diagonals are common to the same vertices, Thus there are 9 unique in a hexagon.

The formula for the number of diagonals of a polygon is

2

n(n−3)

⇒n= number of sides of a polygon ⇒

2

6(6−3)

⇒9

The diagonal of a square formula, is d = a√2; where 'd' is the diagonal and 'a' is the side of the square

When a square is circumscribed by a circle , the diagonal of the square is equal to the diameter of the circle.

To find the length of the diagonal (or hypotenuse) of a right triangle, substitute the lengths of the two perpendicular sides into the formula a2 + b2 = c2
