Answer 2

Answer:

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
