Why is a tetrahedron a platonic solid?
Because a tetrahedron is a triangular based pyramid that has 4 identical faces and 4 faces meet at all the vertices.
A pyramid has how many faces and sides?
A rectangular pyramid has five faces. Sides are the same things as faces. A pyramid with a triangular base has 4 faces. This is the more common type of pyramid in mathematics, as it is a platonic solid.
Are all pyramids platonic solids?
no
What are platonic solid hexahedron B icosahedron octahedron tetrahedron dodecahedron none of these?
They all are, with 6, 20, 8, 4 and 12 faces respectively.
How many regular 3d shapes are there?
There are five Platonic solids: Tetrahedron (or triangular pyramid): 4 triangular faces Cube: 6 square faces Octahedron: 8 triangular faces Dodecahedron: 12 pentagonal faces Icosahedron: 20 triangular faces. Although not a Platonic solid, some people consider a sphere to be a regular 3d shape.
Why is a tetrahedron a platonic solid?
Because a tetrahedron is a triangular based pyramid that has 4 identical faces and 4 faces meet at all the vertices.
What are the 5 names of the platonic solid?
Tetrahedron (4 faces), Cube (6), Octahedron (8), Dodecahedron (12) and Icosahedron (20).
A pyramid has how many faces and sides?
A rectangular pyramid has five faces. Sides are the same things as faces. A pyramid with a triangular base has 4 faces. This is the more common type of pyramid in mathematics, as it is a platonic solid.
Are all pyramids platonic solids?
no
What are platonic solid hexahedron B icosahedron octahedron tetrahedron dodecahedron none of these?
They all are, with 6, 20, 8, 4 and 12 faces respectively.
What 3D shape has 6 edges 4 faces 4 vertices?
Tetrahedron - basic to theory of chemical bonds and one of the classic Platonic solid shapes
What are the three types of polygons that can be the faces of a Platonic solid?
The polygons are the equilateral triangle, the square, and the regular pentagon. The faces of these platonic solids are made from the following polygons: tetrahedron - 4 triangles cube - 6 squares octahedron - 8 triangles dodecahedron - 12 pentagons icosahedron - 20 triangles
How many regular 3d shapes are there?
There are five Platonic solids: Tetrahedron (or triangular pyramid): 4 triangular faces Cube: 6 square faces Octahedron: 8 triangular faces Dodecahedron: 12 pentagonal faces Icosahedron: 20 triangular faces. Although not a Platonic solid, some people consider a sphere to be a regular 3d shape.
What is a solid figure with 6 edges?
A tetrahedron is a solid figure with 6 edges. There's no such thing as solid edges. A tetrahedron is a triangular pyramid, with 4 vertices, 6 edges and 4 triangular faces. In a regular tetrahedron (the first Platonic solid) all triangles are equilateral.
Meaning of each platonic solid?
There are 5 platonic solids which are the only 5 regular polyhedra (possible).Plato attributed 4 of them to the 4 elements:Fire ≡ TetrahedronEarth ≡ CubeAir ≡ OctahedronWater ≡ IcosahedronAristotle added the fifth element "Ether" saying the heavens were made of it; he did not associate the fifth platonic solid, the Dodecahedron, to it.
Which solid has 1 square face and 4 triangular faces?
The solid shape that has one square face and four triangular faces is called a pyramid. If you were to have a shape that had four triangular faces and no square face, it would be called a triangular pyramid.
What are platonic solids and what do they look like?
The five Platonic solids are regular polyhedra. They are convex shapes which are created from regular polygonal faces, such that the number of faces meeting at each face is the same.The five are:tetrahedron - 4 triangular faces;hexahedron (or cube - 6 square faces;octahedron - 8 triangular faces,dodecahedron - 12 pentagonal facesicosahedron - 20 triangular faces.To see their images, search Google for Platonic Solids.
