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.
What shapes can be created from a dodecahedron?
A cross-section of the dodecahedron can be an equilateral triangle, a square, a regular pentagon, a regular hexagon (two ways), or a regular decagon. The planar projection of a dodecahedron can be a regular decagon.
Is a dodecahedron a 4D shape?
You see, a 3D object has a 2D surface, whereas a 4D object has a 3D surface (an nD object has an (n-1)D surface). So while a dodecahedron has 12 faces which are pentagons, a 120-cell has 120 “faces” which are dodecahedra (called cells, since they are 3D).
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.
Is a dodecahedron a real shape?
A Dodecahedron is a 3D shape with twelve faces. Each of those faces is a regular pentagon. A pentagon is a 2D shape with five sides.
What is dodecagon shape?
A 12 sided shape is a polygon called a dodecagon. Basically, a dodecagon is a polygon made up of 12 sides, 12 angles, and 12 vertices. The name of this 12-sided shape comes from the Greek words ‘dodeka’ and ‘hedra’, that mean ‘twelve’ and ‘seat/base’.
What’s 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.
Why is a dodecahedron called a dodecahedron?
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.
What shape is a d12?
The standard form of the d12 is a regular dodecahedron, which is a Platonic solid whose faces are twelve regular pentagons. The sum of the numbers on opposite faces is usually 13. A d12 shaped like a rhombic dodecahedron.
Can a dodecagon be used to tile a flat surface?
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.
What is the definition for dodecahedron?
Definition of dodecahedron
: a solid having 12 plane faces.
What’s bigger than a dodecahedron?
In geometry, the rhombicosidodecahedron is an Archimedean solid, one of thirteen convex isogonal nonprismatic solids constructed of two or more types of regular polygon faces. It has 20 regular triangular faces, 30 square faces, 12 regular pentagonal faces, 60 vertices, and 120 edges.

What does a Hexahedron look like?
A hexahedron is a polyhedron with six faces. The unique regular hexahedron is the cube. Two hexahedra can be built from regular polygons with equal edge lengths: the equilateral triangular dipyramid and pentagonal pyramid. Rhombohedra are a special class of hexahedron in which opposite faces are congruent rhombi.
What is an irregular dodecagon?
An irregular dodecagon has twelve sides of different lengths and varying interior angles.
Is a dodecahedron a prism?
In geometry, a dodecahedral prism is a convex uniform 4-polytope. This 4-polytope has 14 polyhedral cells: 2 dodecahedra connected by 12 pentagonal prisms. It has 54 faces: 30 squares and 24 pentagons. It has 80 edges and 40 vertices.
What 3D shape has 20 sides?
An Icosahedron is a 3D shape that has 20 faces. The name comes from the Greek word eikosi, meaning ‘twenty’, and hedra, meaning ‘seat’.
Where does the word dodecahedron come from?
dodecahedron (n.)
“solid having twelve faces,” 1560s, from Greek dōdeka “twelve” (see dodeca-) + hedra “seat, base, chair, face of a geometric solid,” from PIE root *sed- (1) “to sit.” Related: Dodecahedral.
Can a dodecahedron Tessellate?
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.
How many symmetries does a dodecahedron have?
Number of faces | Number of edges | |
---|---|---|
Cube | 6 | 12 |
Octahedron | 8 | 12 |
Dodecahedron | 12 | 30 |
Icosahedron | 20 | 30 |
Which of the following is a dodecagon?
A dodecagon is a polygon with 12 sides, 12 angles, and 12 vertices. The word dodecagon comes from the Greek word “dōdeka” which means 12 and “gōnon” which means angle. This polygon can be regular, irregular, concave, or convex, depending on its properties.
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”.
How many degrees is a dodecagon?
How many faces does a dodecahedron?
How many faces does a dodecagon?
Dodecahedron – any polyhedron with 12 faces.
What shape is a d100?
The d100 from the standard 7-dice set is a pair of 10-sided dice (in the standard pentagonal trapezohedral shape), one of which is numbered with the integers from 1 to 10 and the other of which has faces numbered in multiples of 10 (00, 10, 20, 30 and so on to 90).
What are the angles in a dodecahedron?
In a dodecahedron, all of the angles, a, b, g, are equal and are 108 degrees. This is due to the fact that each of the faces is a regular pentagon and in a regular pentagon each angle is , where n is 5. and so q = 116.57 degrees.
Which shape Cannot be used for tiling?
There are no whole numbers between 2 and 3, so no regular polygon with more than eight sides can form a regular tiling. Alas, we have solved our problem! There are only three regular poly- gons that form a regular tiling: equilateral triangles, squares, and regular hexagons.

What is the shape of a d4?
Four-sided dice, abbreviated d4, are the lowest number range version of the classic RPG dice set. This seemingly simple tetrahedron (pyramid shape) is one of the most confusing in the lineup, primarily because there are two main styles of d4s.
Which shapes can be tiled?
Among those that do, a regular tessellation has both identical regular tiles and identical regular corners or vertices, having the same angle between adjacent edges for every tile. There are only three shapes that can form such regular tessellations: the equilateral triangle, square and the regular hexagon.
What is a semiregular tiling?
A semiregular or uniform tiling has one type of vertex, but two or more types of faces. A k-uniform tiling has k types of vertices, and two or more types of regular faces. A non-edge-to-edge tiling can have different-sized regular faces.

Is a dodecagon a convex polygon?
Like other polygons, a dodecagon can be classified as regular or irregular. 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. None of the interior angles is greater than 180°.

A regular dodecagon polygon has 12 equal sides and has 12 equal measures of angles. Irregular dodecagons have unequal sides and angles. Also, a dodecagon can be a convex polygon or concave polygon. The sum of all the interior angles of the dodecagon is equal to 1800°.
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.
