What are the angles in a dodecahedron?
A regular dodecahedron or pentagonal dodecahedron is a dodecahedron that is regular, which is composed of 12 regular pentagonal faces, three meeting at each vertex….
| Regular dodecahedron | |

What is dodecahedron polyhedron?
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 faces does a snub dodecahedron?
92 faces
The Snub Dodecahedron contains the original Dodecahedron’s 12 regular pentagonal faces, and the 80 equilateral triangle faces added to create the solid. This is a total of 92 faces. The original Dodecahedron has 20 vertices.
How many sides does a snub dodecahedron have?
The snub dodecahedron is an Archimedean solid consisting of 92 faces (80 triangular, 12 pentagonal), 150 edges, and 60 vertices. It is sometimes called the dodecahedron simum (Kepler 1619, Weissbach and Martini 2002) or snub icosidodecahedron.
How do you find the angle of a regular dodecahedron?
[insert carefully drawn regular dodecagon] You can use this generic formula to find the sum of the interior angles for an n-sided polygon (regular or irregular): Sum of interior angles = (n-2) x 180° Sum of interior angles = 10 x 180° = 1800°
What are the angles between faces of a dodecahedron?
Table of polyhedron dihedral angles
| Name | Schläfli symbol | dihedral angle – exact in bold, else approximate (degrees) |

| Platonic solids (regular convex) | ||
| Hexahedron or Cube | {4,3} | 90° |

What does a 12 sided polygon look like?
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 does dodecahedron look like?
A dodecahedron is a three-dimensional figure having twelve faces that are pentagonal in shape. All the faces are flat 2-D shapes.
What is the biggest polyhedron?
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.
How many sides does a truncated dodecahedron have?
In geometry, the truncated dodecahedron is an Archimedean solid. It has 12 regular decagonal faces, 20 regular triangular faces, 60 vertices and 90 edges.
