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).

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

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.
What is a platonic shape with 4 faces?
A Platonic shape with four faces is known as a tetrahedron. It consists of four triangular faces, with each face being an equilateral triangle. All edges of a tetrahedron are of equal length, and it is one of the five Platonic solids, which are characterized by their regularity and symmetry. The tetrahedron is the simplest three-dimensional shape in geometry.
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.
