How many lines of symmetry does a dodecahedron have?
A dodecahedron has 30 lines of symmetry. This is because each face of a dodecahedron is a regular pentagon, which has 5 lines of symmetry. Therefore, each face contributes 5 lines of symmetry, and since a dodecahedron has 12 faces, the total number of lines of symmetry is 5 x 12 = 30.
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).
What 3D shape that has 12 faces?
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.
Which shape has no face with parallel edges but has parallel edges in the shape?
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.
How many faces does a dodecahedron have?
A dodecahedron has 12 regular pentagonal faces, 20 vertices, and 30 edges. Three faces meet at each vertex.
What describes each face on a dodecaedron?
A dodecahedron has twelve regular pentagonal faces.
How many sides of each face does a dodecahedron have?
A dodecahedron is a 12 side polyhedron. A regular dodecahedron has regular pentagons (5 sides) for each face.
How many sides on each face does a dodecahedron have?
Five sides.
How many lines of symmetry does a dodecahedron have?
A dodecahedron has 30 lines of symmetry. This is because each face of a dodecahedron is a regular pentagon, which has 5 lines of symmetry. Therefore, each face contributes 5 lines of symmetry, and since a dodecahedron has 12 faces, the total number of lines of symmetry is 5 x 12 = 30.
How face does a dodecahedron?
A dodecahedron has 12 faces.
How would you describe the face on an dodecahedron?
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)
What is the face shape of a dodecahedron?
A dodecahedron has pentagonal faces.
Why is the expression twelve times five divided by three used to find the verticies of a dodecahedron?
A dodecahedron has 12 faces. Each face is a pentagon (5 sides). Each vertex is formed where three faces meet.
Does a dodecahedron have triangular face?

How many face does an dodecahedron?
12 faces.
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).
Does a dodecahedron have parallel faces?
A dodecahedron is a polyhedron with 12 faces, each of which is a regular pentagon. In a dodecahedron, the faces are not parallel to each other. The planes of the faces intersect at various angles, giving the dodecahedron its unique shape and properties.
