How many triangles are in a great dodecahedron?
The Great Dodecahedron is one of the four Kepler-Poinsot Polyhedra. The 12 faces of the Great Dodecahedron are made out of 5 triangles each. The model is made out of 60 parts of faces.
What is a dodecahedron in geometry?
The regular dodecahedron, often simply called “the” dodecahedron, is the Platonic solid composed of 20 polyhedron vertices, 30 polyhedron edges, and 12 pentagonal faces, . It is also uniform polyhedron and Wenninger model . It is given by the Schläfli symbol and the Wythoff symbol .

What does dodecahedron look like in the Phantom Tollbooth?
The Dodecahedron is a shape with twelve faces, each one showing a different expression. he lives in Digitopolis and loves solving problems. When Milo, Tock, and the Humbug first met him, he was confused about the fact that Milo had only one face and asked if everyone with one face was called a “Milo”.
How many points are in a Stellated dodecahedron?
What is the shape of the great stellated dodecahedron?
The great stellated dodecahedron is composed of 12 pentagrammic faces with three pentagrams meeting at each vertex. It shares its vertex arrangement with the regular dodecahedron, and it is a stellation of a smaller dodecahedron. It is related to the triakis icosahedron, but with much taller isosceles triangle faces.
How many edges does a dodecahedron have?
The dodecahedron has 30 edges, 20 vertices and 12 faces. Dodeca is a prefix meaning “twelve.”. The dodecahedron is the only polyhedron I know of which is composed entirely of pentagons.
Is the great dodecahedron a triakis icosahedron?
If the great dodecahedron is considered as a properly intersected surface geometry, it has the same topology as a triakis icosahedron with concave pyramids rather than convex ones. The excavated dodecahedron can be seen as the same process applied to a regular dodecahedron.
What is the truncation sequence from the small stellated dodecahedron to its dual?
Here is the truncation sequence from the small stellated dodecahedron to its dual, the great dodecahedron. The Great Dodecahedron is the dual of the small stellated dodecahedron. It is composed of 12 pentagonal faces (six pairs of parallel pentagons), with five pentagons meeting at each vertex.
