Nonagon Has How Many Sides – If the nonagon shape is introduced, it will be introduced to your students starting in fifth grade! The only purpose of introducing it is so that your child can recognize it, and for no other reason. However, I believe that all children should be taught the relationships between different regular polygons.
These connections are for finding the area and angles of regular polygons. In a four-sided regular polygon (square), find the degree value of its interior angle
Nonagon Has How Many Sides
Divide the pattern by the number of sides in a simple polygon, 360 to get the angle in the middle. Then subtract your answer from 180 to get the value of the interior angle.

So even if your child is asked about a 20-sided polygon, they should have the skills to know that the value of that angle will be 180-(360/20).
The detailed steps below take you from basic identification to making Nonagon shapes and more!
They are a nice “breather” on the learning curve, but they are also a great way to reinforce new knowledge in a way that helps your child understand real and basic geometry concepts.
A typical Nonagon is defined by a combination of the number and shape of the sides, the length of the sides and the size of the angles.
Nonagon Infinity’s Missing Line
A regular Nonagon has nine sides of equal length … and nine angles of equal size – all angles are 40 degrees at the center (360/9=40) and interior angles are 140 degrees [180-(360/9) = 140 ]
Once your child is comfortable with how to recognize the shape, offer him some shape worksheets to help him learn to recognize the shape.
2: The perpendicular distance from the center of the nonagon to one of the sides. (In “math speak” this perpendicular distance is called an APOTHEM!) I included 2 in my diagram (there are 9 total in nonagons) and these are the blue lines. You can also see that these apothems are actually the radii of circles inscribed in the nonagon (made in green).
Find the area of one of the isosceles triangles formed by one side of the octagon and find the area of the two straight lines from the center to each vertex to calculate the area of the rhombus. Then multiply that answer by 9, because these triangles are nine in the Nonagon.

Since 9 of these triangles are non-angled, we need to get the area of ALL nine triangles to get their area.
The perimeter of any shape is the sum of all the lengths of that shape, and the Nonagon is no different.
Step 1: Using a ruler and pencil, carefully draw a straight line on the paper. – This is what we call the construction line.
Step 2: Specify a point on this line – this point will be the first of nine vertices.

Step 3: Using the protractor, find a point 140 degrees from the first line using the point indicated in the previous step and draw another construction line.
Step 4: Use your ruler to measure the length of BOTH of these BOTH COMMON SIDES and mark them with dots.
A quick check is to measure the length of all sides with a ruler to make sure your shape is correct. If you’ve done it right, all pages will measure the same!
By using coloring pages, your child can start experimenting with triangles. The first step is to encourage the child to color the triangles in the same color until the shape starts to become “something”.

Starting your own fitness business is an exciting prospect, but it’s not as complicated as some would like. In geometry, a nonagon (/ˈ n ɒ n ə ɡ ɒ n / ) or neagon (/ˈ ɛ n i ə ɡ ɒ) n / ) is a nine-sided polygon, or 9-sided.
The name nonagon is a prefix hybrid form from Latin (nonus, “ninth” + gonon), used synonymously, attested in Frch nonogone in the 16th century and in gloss from the 17th century. The name Neagon is more correctly derived from the Greek word neagonon (εννεα, “nine” + γωνον (γωνία = “corner”).

Normal neagon symmetry. The vertices are colored according to their symmetry positions. The blue mirror is drawn in the center of the vertex, and the purple mirror is drawn along the edges. Gyration orders are given to cter.
Congruent Rotated Nonagons
These 6 symmetries can have 6 different symmetries on the neagon. John Conway noted these in alphabetical and chapter order.
The complete symmetry of the normal form is r18 and the symmetry is not specified a1. Bilateral symmetry is divided by vertices (d for diagonal) or edges (p for perpendicular), and whether reflection lines pass through both edges and vertices. Cyclic symmetries in the central column are denoted by g in the order of ktral rotation.
Each subgroup symmetry allows one or more degrees of freedom for irregular shapes. Only the g9 subgroup has no degrees of freedom, but can see straight edges.
A typical neagon can decorate Euclidean tiles with holes. These holes can be filled with regular hexagons and right triangles. In symmetrohedral notation, this tiling is called H(*;3;*;[2]), where H has *632 hexagonal symmetry in the plane.

A complete graph is usually drawn as a regular Negon with all 36 edges connected. This graph also shows again the orthographic projection of the 8 simplexes with 9 vertices and 36 edges.. A nonagon is also called an enneagon. In many ways enneagon is a more correct term because it uses Greek roots for both prepositions (
The nonagon is rarely used in most geometry texts, but it is an interesting shape whether you are studying a regular nonagon or an irregular nonagon.
A nonagon has nine straight sides of the same length. If all the sides are the same length, you will have a regular nonagon. If the lengths of the sides are different, you will have an irregular nonagon.
Irregular ridges may have sides of different lengths and internal angles of different sizes. But even such strange forms are not simple:
