## What is the angle sum of a polygon with 9 sides?

ANSWER: The sum of the angles is 1260°. Therefore the sum of the angles in 9 sided polygon is 1260°.

**Which is a polygon with 9 sides?**

nonagon

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.

### How does a nonagon look like?

It has four equal sides and four right angles, each measuring 90 degrees. A regular nonagon is a nine-sided shape with equal sides and equal angles of 140 degrees each. Each interior angle measure of a regular nonagon is 140 degrees.

**What is the sum of the angle measures in a nonagon 9 sides )?**

1260°

A nonagon consists of 9 angles. The sum of angles of a nonagon is 1260°.

#### What is an irregular nonagon?

Irregular nonagon A nonagon in which all sides are not equal and all angles are not equal. The measure of its angles are different but total sum of all its interior angles is always 1260°.

**How many sides and angles does a regular nonagon have?**

9 sides

A nonagon is a polygon made up of 9 sides and 9 angles.

## How many degrees does a 9 sided nonagon have?

A nonagon in which all sides are not equal and all angles are not equal. The measure of its angles are different but total sum of all its interior angles is always 1260°. Against this background, how many degrees are in a 9 sided polygon? In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon. Nonagon.

**How many degrees are in a 10 sided polygon?**

In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, “ten angles”) is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°. Read full answerThanks (21)

### How to calculate the interior angles of a 9 sided polygon?

The sum of interior angles = (n-2)*180 where n is the number of sides the polygon has e.g. n=9 for a nonagon (9 sided shape) Please note sometimes the formula for interior angles is written as (2n-4) right angles.

**What is the name of a 9 sided polygon?**

A nonagon is also called enneagon, which is derived from a Greek word called enneagonon, which means nine corners. The first use of the word nonagon dates back to the early 17th century, and has a Latin prefix (nona) and a Greek suffix (gon), making it a polygon with nine sides and nine angles.
