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.
Does a dodecahedron have triangular face?

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.
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.
