A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. 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 many diagonals does a dodecagon?
Properties | Values |
---|---|
Number of diagonals | 54 |
Number of triangles | 10 |
Sum of the interior angles | 1800° |
What is the degree of Dodecagons?
To be considered a regular dodecagon, each side has to have the same length, and therefore, each angle will have the same measurement, which happens to be 150 degrees. This would make the sum of its interior angles equal to 1800 degrees.
How many sides does a nonagon have?
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.
What is the difference between dodecagon and dodecahedron?
A dodecagon is a two-dimensional (flat) polygon with 12 sides. A dodecahedron is a three-dimensional (solid) object with 12 sides.

How many sides does a Megagon have?
A megagon or 1 000 000-gon is a polygon with one million sides (mega-, from the Greek μέγας, meaning “great”, being a unit prefix denoting a factor of one million).
What is the side of decagon?
A decagon can be defined as a polygon having ten sides, ten interior angles and ten vertices.
What does dodecahedron look like?
‘ So, a dodecahedron is a three-dimensional solid that has twelve flat faces. It also has straight edges and sharp vertices, or corners. … He doesn’t just have twelve flat sides; each of his sides has a face with a different expression.
Is a dodecahedron a Platonic solid?
Platonic solid, any of the five geometric solids whose faces are all identical, regular polygons meeting at the same three-dimensional angles. Also known as the five regular polyhedra, they consist of the tetrahedron (or pyramid), cube, octahedron, dodecahedron, and icosahedron.
What 3d shape has 12 sides?
In geometry, a dodecahedron (Greek δωδεκάεδρον, from δώδεκα dōdeka “twelve” + ἕδρα hédra “base”, “seat” or “face”) or duodecahedron is any polyhedron with twelve flat faces. The most familiar dodecahedron is the regular dodecahedron with regular pentagons as faces, which is a Platonic solid.

How many sides does the earth have?
Powered by. Any circle drawn around the Earth divides it into two equal halves called hemispheres. There are generally considered to be four hemispheres: Northern, Southern, Eastern, and Western. The Equator, or line of 0 degrees latitude, divides the Earth into the Northern and Southern hemispheres.
Is a five point star a decagon?
A five-pointed star (☆), geometrically an equilateral concave decagon, is a common ideogram in modern culture. Comparatively rare in classical heraldry, it was notably introduced for the flag of the United States in the Flag Act of 1777 and since has become widely used in flags.
What is a nonagon shape?
A nine-sided shape is a polygon called a nonagon. It has nine straight sides that meet at nine corners, or vertices. The word “nonagon” comes from the Latin word “nona”, meaning nine, and “gon”, meaning sides. So it literally means “nine sided shape”.

Can a dodecahedron Tessellate?
Properties. The rhombic dodecahedron is a zonohedron. … The rhombic dodecahedron can be used to tessellate three-dimensional space: it can be stacked to fill a space, much like hexagons fill a plane. This polyhedron in a space-filling tessellation can be seen as the Voronoi tessellation of the face-centered cubic lattice …
