How many Vertices does dodecahedron?
The number of vertices ranges from 8 to 20.
What is the number of an icosahedron or the number of vertices of a dodecahedron?
An icosahedron has 20 faces, 30 edges, and 12 vertexes. 5 polygons meet at each vertex and each face has 3 vertexes (therefore made of triangles). A dodecahedron has 12 faces, 30 edges, and 20 vertexes. 3 polygons meet at each vertex and each face has 5 vertexes (therefore made of pentagons).
How many vertices does an icosahedron have?
There is no simple answer to this question.Polyhedra are named according to the number of faces that they have. An icosahedron is a 3-dimensional shape with 20 faces. It could be in the form of a pyramid with a 19-sided polygon as base. In that case, it has 20 vertices. Or it could be in the form of a prism with 18-sided polygons as base and in that case it has 36 vertices. There are several million different configurations, and the number of vertices varies.The regular icosahedron is a Platonic solid with faces that are equilateral triangles. That has 12 vertices.
Describe two polygons with vertices and sides?
A triangle is the simplest polygon with three vertices and 3 sides. A dodecahedron has 12 vertices and 12 sides. There is no limit to the number of vertices and sides that a polygon can have - except that the two numbers must be the same.
What do you notice about the number of sides and the number vertices apolygon has?
The number of sides and vertices are the same
Number of vertices of a regular dodecahedron?
Twenty.

The number of Platonic solids?
There are 5 platonic solids. They are: Tetrahedron, Octahedron, Icosahedron, Cube, and Dodecahedron
How many angles does an icosahedron have?
An icosahedron is named after the number of faces that it has. The number of vertices will depend on the exact configuration of the shape. For example, a icosahedron in the form of a prism, with 18-gons as bases, will have 36 vertices. A pyramid with a 19-gon base will have 20 vertices. A bipyramid with a decagon base will have 12 vertices. There are very many more possible shapes.
How many corners has a icosahedron have?
The name most mathematicians use for the corners is vertices. An icosahedron is a 20 sided polyhedron. It is one of a group of special solids known as platonic solids. So, the icosahedron has 20 faces and 12 vertices or "corners" as you call them. It has 30 edges. There is an interesting formula that relates the number of edges, vertices and faces. V+F-2=E where V is the number of vertices, F the number of faces, and E the number of edges. In the case of the icosahedron we have 12+20-2=12+18=30 just as we expected. The nice thing about the formula is if you know two of these things, you can always find the third!
How many vertices edges and faces does a dodehedron have?
A dodehedron does not exist. A regular dodecahedron has 20 vertices, 30 edges and 12 faces. A dodecahedron must have 12 faces, but it can have any number from 8 to 20 vertices and so 18 to 30 edges.

two polygons by the number ofvertices and sides each has?
A triangle is the simplest polygon with three vertices and 3 sides. A dodecahedron has 12 vertices and 12 sides. There is no limit to the number of vertices and sides that a polygon can have - except that the two numbers must be the same.
How many edges of dodecahedron?
A dodecahedron is a 3-dimensional shape with 12 polygonal faces. There are approx 6.4 million topologically different convex dodecahedra, plus concave ones. These have between 8 to 20 vertices and the number of edges is 10 more than the number of vertices - so between 18 and 30.
How many vertices does a dodechaedron have?
you spelled the word strangely so i am not sure what shape you mean a dodecagon has 12 sides a decagon has ten sides a dodecahedron is, i think, a 3-D shape but i don't recall the number of sides it has ============= A dodecahedron has 12 vertices.
How are platonic solids related?
One way in which Platonic solids are related is by duality. To construct the dual of a Platonic solid take the vertices of the dual to be the centres of the faces of the original. The lines joining adjacent centres of the original form the edges of the dual. In this way, the numbers of faces and vertices are swapped while the number of edges remain the same.A tetrahedron is its own dual.A hexahedron (cube) and octahedron from a dual pair.A dodecahedron (cube) and icosahedron from a dual pair.One way in which Platonic solids are related is by duality.
