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).
The 3D shape that has 12 faces is called a dodecahedron. It is a polyhedron with 12 regular pentagonal faces. Each face of a dodecahedron is a regular polygon with five sides of equal length and five equal interior angles.
A regular dodecahedron, for example. Each face is a regular pentagon so no face has parallel sides. However, the edges on opposite faces are parallel to one another.
A dodecahedron has 12 regular pentagonal faces, 20 vertices, and 30 edges. Three faces meet at each vertex.
A dodecahedron is a generic term which describes a 3-dimensional shape with 12 polygonal faces. There are approx 6.4 million topologically different convex dodecahedra plus concave ones. They can have 8 to 20 vertices and 18 to 30 edges.
A dodecahedron has twelve regular pentagonal faces.
A dodecahedron is a 12 side polyhedron. A regular dodecahedron has regular pentagons (5 sides) for each face.
Five sides.
A dodecahedron has 12 faces.
I assume you mean a regular dodecahedron. A regular dodecahedron has twelve faces, each of which are regular* pentagons. *(all sides are congruent, all angles are congruent)
A dodecahedron has pentagonal faces.
No, the faces of a regular dodecahedron are pentagonal.No, the faces of a regular dodecahedron are pentagonal.No, the faces of a regular dodecahedron are pentagonal.No, the faces of a regular dodecahedron are pentagonal.
A dodecahedron has 12 faces. Each face is a pentagon (5 sides). Each vertex is formed where three faces meet.
12 faces.
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).
A dodecahedron's faces can be considered congruent of each other. Each face of the twelve-sided Platonic solid is a perfect pentacle, each angle at 72 degrees, each side equal with the others. All sides of the 12 pentacles join to form the dodecahedron. The sides and angles must remain equal, thus proving more than congruence in its form. As I write this, I'm looking at a dodecahedron on my desk. It is part of my dice set when I play Dungeons and Dragons.
