# What is a nonagon shape look like?

## What is a nonagon shape look like?

An irregular nonagon is a nine-sided shape that does not have equal sides or angles. One real world example of an irregular nonagon is the US Steel Building in Pittsburgh, Pennsylvania. It looks like a triangle with each corner indented.

## What kind of shape is a nonagon?

nine sided shape
A nine sided shape is a polygon called a nonagon. It has nine straight sides that meet at nine corners. The word nonagon comes from the Latin word “nona”, meaning nine, and “gon”, meaning sides. So it literally means “nine sided shape”.

What is nonagon for kids?

A nonagon or 9-gon is a shape with 9 sides and 9 corners.

What are the measurements of a nonagon?

All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1260 degrees (from above)… And there are nine angles… So, the measure of the angle of a regular nonagon is 140 degrees.

### Is a nonagon concave or convex?

No line containing any of the sides will pass through the interior of the quadrilateral, so it is convex. Example 1a: There are 9 sides, so this is a nonagon. A line containing some of the sides will pass through the interior of the nonagon, so it is concave.

### Is nonagon simple or complex?

Nonagon angles Every simple nonagon (not complex) can have it’s interior divided into seven triangles. You can find the sum of interior angles by multiplying 7 × 180° 7 × 180 ° , which is how you get 1260° .

How is a nonagon?

Nonagon – Definition with Examples A nonagon is a polygon made up of 9 sides and 9 angles. Nonagon = Nona + gon where Nona means nine and gon means sides.

What is a nonagon and Decagon?

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.

## How do you find the measure of each interior angle of a nonagon?

Since each of the nine interior angles in a regular nonagon are equal in measure, each interior angle measures 1260° ÷ 9 = 140°, as shown below.
