How Many Sides Do A Nonagon Have – In geometry, a nonagon (/ˈn ɒ n ə ɡ ɒ n / ) or neagon (/ˈ ɛ n i ə ɡ ɒ n / ) is a nine-sided or 9-sided polygon.

The name nonagon is a hybrid formation of the prefix from the Latin (nonus, “ninth” + gonon), used equally and already confirmed in the 16th century in Frch nonogone and in English from the 17th century. The name neagon comes from the Greek neagonon (εννεα, “nine” + γωνον (from γωνία = “edge”) and is probably more correct,

, which is not Fermat’s first product), has very old construction methods that produce very close approximations.

Symmetry of a regular neon. Vertices are colored according to their symmetry positions. The blue mirrors are drawn from the top and the purple mirrors are drawn from the corner. Crying orders are given in cter.

These 6 symmetries can be seen in 6 different symmetries of neon. John Conway shows them with a letter and a group order.

The complete symmetry of the regular form is r18 and symmetry a1 is not shown. Dihedral symmetries are divided according to whether they pass through vertices (d for diagonal) or vertices (p for perpendicular) and i where reflection lines pass through both vertices and vertices. The rotational symmetry is shown in the middle column as g for the rotational order of the krals.

Each symmetry subgroup allows one or more degrees of freedom for irregular shapes. Only the subgroup g9 has no degrees of freedom, but can be seen as directed edge.

### A Nonagon Has Sides

A regular Neagon can construct a Euclidean tiling with gaps. These spaces can be filled with regular hexagons and isosceles triangles. In symmetried notation, this tiling is called H(*;3;*;[2]), and H restores the hexagonal *632 symmetry of the plane.

Complete graphics are often represented as regular neons with all 36 vertices connected. This graph also re-illustrates the orthogonal projection of 9 vertices and 36 edges of the 8-simplex. A nonagon or 9-gon is a nine-sided polygon with nine interior angles that add up to 1260°. Nonagons are also called enneagons. In many ways, enneagon is a more accurate term because it uses Greek roots for both its prefix (ennea-, meaning nine) and its suffix (-gon, angle).

Nonagons are rarely used in most geometry texts, but this is an interesting shape whether you are examining regular nonagons or irregular nonagons.

## Angles, Areas And Diagonals Of Regular Polygons

Nonagon has nine right sides of equal length. If the sides have the same length, then you have a regular nonagon. If the sides are different lengths, then you have irregular bread.

Each obtuse angle has nine interior angles that add up to 1260° and nine exterior angles that add up to 360°.

It is very nearly a circle, but not quite. The interior angles are each 140°. You can check this because 1260° ÷ 9 (angle) = 140°.

#### What Is A Nonagon

The central angle is 40° (which you can divide 360° by 9). This means you can make a regular angle with 7 similar triangles with two 70° angles and one 40° angle.

Irregular polygons can have sides of different lengths and internal angles of different sizes. However, even unusual forms such as these are not normal:

The only purpose of introducing it is so that your child can identify it, not for any reason. However, I think that all children should also learn the relationship between different regular polygons.

#### Congruent Rotated Nonagons

These links are mainly for finding areas and angles of regular polygons. In a regular four-sided (square) polygon, the degree values ​​of its internal angles are found

The model is simply divided by 360 by the number of sides of a regular polygon to find the angles at the center. Then subtract your answer from 180 to get the value of the interior angles.

So, even if your child is asked about a 20-sided polygon – they should now have the skills to know that the value of the angle will be 180- (360/20).

The detailed steps below will take you from the basic introduction to making Nonagon patterns and more!

These are good “breathers” on the learning curve, but they are a great way to reinforce new knowledge that your child can use in real life and include understanding basic geometry concepts.

A regular nonagon is defined by the combination of the number of sides of the shape, the length of the sides and the size of its angles.

A regular angle has NINE sides of equal length … and NINE angles of equal measure – all central angles 40 degrees (360/9=40), interior angles 140 degrees  [180-(360/9) = 140 ]

Once your child is comfortable with recognizing this shape, give them the shape worksheet to see how they identify it.

2: The perpendicular distance between the center of the Nonagon and one of its sides. (In “mathematics speak” this perpendicular distance is known as an APOTHEM!)  In my diagram I put 2 (there are only 9 per corner) and these are the blue lines. You can also see that these Apothems are actually the circle rays written on the bread (made in green).

The area of ​​an isosceles triangle is calculated by finding the area of ​​one of the isosceles triangles formed by an octagon side and two lines drawn from the center point to each vertex. Then you multiply this answer by 9 because there are nine of these triangles in Nonagon.

We have 9 triangles in the nonagon, so to find its area, we need to find the area of ​​ALL nine triangles.

The perimeter of any shape is simply the sum of all the lengths of the shape – and the Nonagon is no different.

#### Irregular Convex Nonagon

Step 1:  Using a ruler and pencil, draw a straight line on your paper. – We call this construction line.

Step 2: Mark a point on this line – this point will be the first nine vertices.

Step 3:  Using your protractor, find a point at 140 degrees from your first line using the point you marked in the previous step and draw another construction line.

Step 4: Using your tape measure, measure the length of your unknown side along these TWO lines and mark with a dot.

A quick check to make sure your shape is accurate is to measure all the side lengths with your tape measure. If you did it right, all sides will be the same!

Using coloring sheets allows your child to start experimenting with triangles. A great first step is to encourage your child to color in adjacent triangles of the same color until the shapes look like “something”.

Maybe it’s a rectangle or a house! By doing this, your child will begin to understand the relationship between different shapes. You’ll find some great free geometric coloring pages to download and get started.
