# Is a dodecahedron a 2-D shape?

## Is a dodecahedron a 2-D 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. Like all 3D shapes, it’s possible to assemble a dodecahedron using a net.

## What does a dodecahedron look like?

Dodecahedrons Have 12 Pentagonal Faces As you’ll know if you’ve ever been to Washington, D.C., pentagons are 2-D shapes with five straight edges that form five angles at the corners. Dodecahedrons (pronounced dow·deh·kuh·hee·druhns) are three-dimensional bodies containing a dozen flat faces — all shaped like pentagons.

What kind of shape has 12 sides?

dodecagon
In geometry, a dodecagon or 12-gon is any twelve-sided polygon..

### What describes each face on a dodecahedron?

The regular dodecahedron is a Platonic solid having of 20 vertices, 30 edges, and 12 faces. Each face is a regular pentagon. The dodecahedron is the dual of the icosahedron which has 12 vertices, 30 edges and 20 faces. Each face of an icosahedron is an equilateral triangle.

### What shapes are on the faces of a dodecahedron?

Yes, a dodecahedron is a polyhedron because a polyhedron is a solid shape whose faces are all polygons. All the faces of the dodecahedron are pentagons, which is a regular polygon.

How many sides of each face does a dodecahedron have?

In geometry, a dodecahedron (Greek δωδεκάεδρον, from δώδεκα dōdeka “twelve” + ἕδρα hédra “base”, “seat” or “face”) 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.

#### Does dodecahedron have parallel faces?

dodecahedron A crystal form composed of 12 rhomb-shaped faces, each face intersecting two of the crystallographic axes and being parallel to the third. It belongs to the cubic (isometric) system.
