How many diagonals does a hexagon have 6?
9
Now, using the relation between the number of diagonals and number of sides . $ \Rightarrow {D_n} = \dfrac{{n\left( {n – 3} \right)}}{2}$ , where ${D_n}$ is a number of diagonals. For regular hexagon values of n=6. Therefore, in a regular hexagon the number of diagonals is 9.
What is a hexagon with 6 sides?
In geometry, a hexagon (from Greek ἕξ, hex, meaning “six”, and γωνία, gonía, meaning “corner, angle”) is a six-sided polygon or 6-gon. The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°….Hexagon.

How many diagonals does a 6 side have?
A diagonal of a polygon can be defined as a line segment joining two vertices. From any given vertex, there are no diagonals to the vertex on either side of it, since that would lay on top of the side….Solved Examples.
| Polygon Name | Number of Sides | Number of Diagonals |
|---|---|---|
| Pentagon | 5 | 5 |
| Hexagon | 6 | 9 |
| Heptagon | 7 | 14 |
What are the diagonals of a hexagon?
For example, in a hexagon, the total sides are 6. So, the total diagonals will be 6(6-3)/2 = 9.
What is the number of diagonals of a hexagon?
9 diagonals
If all the sides of a hexagon are equal and angles are the same then the hexagon is called a regular hexagon. A regular hexagon has a total number of 9 diagonals. The sum of all interior angles of a regular hexagon is 720 degrees. Also, each interior angle is 120 degrees.
What are the characteristics of a hexagon?
Properties of Hexagon
- It has six sides, six edges, and six vertices.
- All the side lengths are equal or unequal in measurement.
- All the internal angles are equal to 120° in a regular hexagon.
- The sum of the internal angles is always equal to 720°
- All the external angles are equal to 60° in a regular hexagon.
What are three attributes of a hexagon?
The three attributes of a hexagon are:
- It has 6 sides.
- It has 6 angles.
- It has 6 corners.
What are the vertices of a hexagon?
6
Hexagon/Number of vertices
How many diagonals does a 8 sided polygon have?
20 diagonals
∴ The octagon has 20 diagonals.
Are diagonals of regular hexagon equal?
Hexa means six and therefore a hexagon is supposed to have six side. The angles of each side of a regular hexagon are equal. A regular hexagon has nine diagonals. Since all angles are equal in a regular hexagon, each angle is 120o and the summation of all the interior angles is 720o.
