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 things are shaped like a nonagon?

Is a nonagon a regular shape?
In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon.Nonagon. Regular enneagon (nonagon) A regular enneagon (nonagon) Type Regular polygon Edges and vertices 9 Schläfli symbol {9}.
Is a nonagon a 9 sided shape?
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.
How do you write a nonagon?
Nonagon = Nona + gon where Nona means nine and gon means sides.
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 is nonagon vertices?
9
What is a convex nonagon?
Nonagons and other polygons can also be classified as either convex or concave. If all interior angles of a nonagon are less than 180°, it is convex. If one or more interior angles is larger than 180°, it is concave. A regular nonagon is a convex nonagon.
What are the measurements of a nonagon?
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 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)Jun 18, 2020.
How many vertices have a nonagon?
9
How many angles does a nonagon have?
A nonagon has nine straight sides and nine vertices (corners). It has nine angles inside it that add up to 1260°.
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.
What is the sum of the exterior angles of a nonagon?
The sum of the measures of the exterior angles is 360. A convex regular nonagon has 9 congruent exterior angles. 9n = 360 n = measure of each exterior angle n = 40 Divide each side by 9. The measure of each exterior angle is 40.
Is a Dodecagon convex or concave?
A dodecagon can also be classified as convex or concave. A convex dodecagon is a polygon where no line segment between any two points on its boundary lies outside of it.Dodecagon classifications. Regular dodecagon Irregular dodecagon All sides and interior angles are congruent Sides and angles have various lengths.
What is the interior angle of nonagon?

What’s a 10 sided shape?
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°. A self-intersecting regular decagon is known as a decagram.

How many edges does a nonagon have?
9
How do you draw a Hendecagon?
(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”.)Hendecagon. Regular hendecagon Properties Convex, cyclic, equilateral, isogonal, isotoxal.
What is shape of octagon?
Octagon is a polygon in geometry, which has 8 sides and 8 angles. That means the number of vertices is 8 and the number of edges is 8. All the sides are joined with each other end-to-end to form a shape. These sides are in a straight line form; they are not curved or disjoint with each other.
What is a 100 sided shape called?
Regular hectogon Regular hectogon Type Regular polygon Edges and vertices 100 Schläfli symbol {100}, t{50}, tt{25} Coxeter–Dynkin diagrams.
How many degrees is a regular nonagon?
1260°.
What is the difference between a dodecagon and a dodecahedron?
While a dodecagon has 12 faces and 12 vertices, the dodecahedron consists of 12 faces with each face consisting of 5 edges along with 20 vertices. One of the main differences is that dodecahedron is a 3D shape and so, unlike the 2-dimensional figure, it also has volume.
What is a 10000 sided shape called?

Can a dodecagon be used to tile a flat surface?
A square is an example of a four-sided regular polygon, with 90-degree angles. There are exactly eight ways to do this using various combinations of regular polygons—triangles, squares, hexagons, octagons, and dodecagons (twelve-sided polygons). Any of these eight combinations would make a nice floor tiling.
Is a dodecagon an irregular shape?
A dodecagon is a 12-sided polygon that encloses space. Dodecagons can be regular in which all interior angles and sides are equal in measure. They can also be irregular, with different angles and sides of different measurements.
Which of the following is a dodecagon?
In geometry, a dodecagon or 12-gon is any twelve-sided polygon.
