## How do you draw a nonagon?

## How many triangles does a nonagon have?

A regular nonagon has up to

**9 congruent triangles**that do not overlap.## How many equal sized angles does a nonagon have?

A regular nonagon shape has 9 equal sides and

**9 congruent angles**. In a regular nonagon, each interior angle measures 140° .## How do you draw a nonagon with a protractor?

Nonagon/Number of vertices

## Is a nonagon a 9 sided shape?

In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is

**a nine-sided polygon or 9-gon**. The name nonagon is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.## 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.## What are the 9 sides of a 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. So it literally means “nine sided shape”.## What is the sum of a nonagon?

1260°

For example, a regular nonagon has 9 sides. From the formula, the sum of the angles is (9 – 2)*180° = 7*180° =

**1260°**. Divided by 9, this is 1260°/9 = 140° so each angle in a regular nonagon has 140°.## What is dodecagon shape?

A dodecagon is

**a 12-sided polygon**. … In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.## How does a Heptagon look like?

The heptagon shape is a plane or two-dimensional shape comprised of

**seven straight sides, seven interior angles, and seven vertices**. A heptagon shape can be regular, irregular, concave, or convex. … All heptagons can be divided into five triangles. All heptagons have 14 diagonals (line segments connecting vertices)## How many lines of symmetry does a nonagon have?

9

Nonagon/Line of symmetry

A regular nonagon has

**9 lines**of symmetry and a rotational symmetry of order 9, meaning that it can be rotated in such a way that it will look the same as the original shape 9 times in 360°. Nine 40° of rotation about the center.## How is dodecagon pronounced?

## What is a Icosagon shape?

In geometry, an icosagon or 20-gon is

**a twenty-sided polygon**. The sum of any icosagon’s interior angles is 3240 degrees.## How do you make a dodecagon?

## Where did the word Dodecagon originate?

English word dodecagon

**comes from English -gon, English dodeca- (Twelve.)**## How do you speak hexagon?

## What is an 11gon?

In geometry,

**a hendecagon (also undecagon or endecagon) or**11-gon is an eleven-sided polygon. (The name hendecagon, from Greek hendeka “eleven” and –gon “corner”, is often preferred to the hybrid undecagon, whose first part is formed from Latin undecim “eleven”.)## What are examples of dodecagon?

A polygon with 12 sides is known as a dodecagon. Therefore, figure (a) is a dodecagon. Example 2: There

**is an open park in the shape of**a regular dodecagon.
