What is Nonagon? – A nonagon is a polygon made up of 9 sides and 9 angles, Nonagon = Nona + gon where Nona means nine and gon means sides. The given nonagon ABCDEFGHI has sides AB, BC, CD, DE, EF, FG, GH, HI, and IA and angles ∠A, ∠B, ∠C, ∠D, ∠E, ∠F, ∠G, ∠H, and ∠I. The blue line segments AC and BD are its diagonals, There are total of 27 diagonals in a nonagon as shown below:

### Does a nonagon have 10 sides?

What is Nonagon? – Nonagon Shape and Properties In geometry, we may come across different as shown in the figure given below. All of these polygons have different properties based on the number of sides and angles they have. A nonagon is a nine sided polygon and it is also called an Enneagon or 9-gon, In other words, a nonagon is a nine sided closed two dimensional figure. Here, a 3-sided polygon is a triangle, 4 sided polygon is a quadrilateral, 5-sided polygon is a pentagon, 6-sided polygon is a hexagon, 7-sided polygon is heptagon, 8-sided polygon is octagon, 9-sided polygon is called a nonagon and a 10-sided polygon is the decagon.

A whole regular chiliagon is not visually discernible from a circle. The lower section is a portion of a regular chiliagon, 200 times as large as the smaller one, with the vertices highlighted. In geometry, a chiliagon () or 1000-gon is a polygon with 1,000 sides.

## What is a 100000000000 sided shape called?

You could also call it a billion-agon if you like, but you might as well just call it a ‘billion sided polygon’ for clarity.

## What is 12 sided shape called?

What is a 12-sided shape? – A 12 sided shape is a polygon called a dodecagon. Basically, a dodecagon is a polygon made up of 12 sides, 12 angles, and 12 vertices. The name of this 12-sided shape comes from the Greek words ‘dodeka’ and ‘hedra’, that mean ‘twelve’ and ‘seat/base’. Dodecagons can be regular, which mean that all the interior angles and sides are equal in measure, and irregular, which means that the angles and sides have different measurements.

#### What is a 9000 sided shape called?

BLOG While the suffix “gon” defines a shape with a specific number of sides and angles, the root “agon” comes from the Greek word meaning “to struggle or fight” (as in agony or antagonist). But in efforts to keep the peace, we’ll be chatting about the:

Hexagon: From the Greek hêx, Heptagon: From the combined Greek heptâ and Latin septem. Octagon: From the Greek octa. Nonagon: From the Latin nonus, it’s also called an enneagon. Another “worth noting” note is that the suffix nona means sleeping sickness. Decagon: A hybrid of the Greek dêka and the Latin decem. While it’s easy to see how we get ten-related words such as decade and decathlon from this, the original Roman calendar only had ten months, which is why our 12 th month is called December.

Anything having equal sides and angles has a name, but most examples (or need) for their usage are rare. A couple of the unwonted include the Icosikaioctagon (28 sides) and the Enakischiliagon (9000 sides).
