What shape has 4 faces which are congrugent triangles?
A four faced figure is a tetrahedron. If they are all congruent triangles, they are all equilateral triangles and it is a regular tetrahedron - one of the 5 Platonic Solids.
How many faces does a polyhydra triangle have?
There are several triangular polyhedra. The simplest is a tetrahedron with 4 faces, but you can have a triangular dipyramid (two tetrahedra stuck together along one face) which has 6 faces. Then there is the icosahedron with 20 faces. The tetrahedron and icosahedron are Platonic solids, but there are many more.
What is a solid figure that has all of its faces congruent?
The Platonic Solids: Tetrahedron, cube, octahedron, dodecahedron and icosahedron.
A cube is the only prism which is a Platonic solid?
No; platonic solids are tetrahedron, cube, octahedron, dodecahedron, icosahedron.
Do the Platonic Solids consist of 7 regular polyhedra?
No. There are only five Platonic Solids; Tetrahedron, Hexahedron, Octahedron, Dodecahedron and Icosahedron, with 4,6,8,12 and 20 faces respectively.
What solids have all triangular faces?
tetrahedron
Which of the following Platonic solids is also a pyramid?
tetrahedron
What are the 5 solids?
The five platonic solids are the Tetrahedron, Hexahedronor Cube, Octahedron, Dodecahedron, and the Icosahedron
The number of Platonic solids?
There are 5 platonic solids. They are: Tetrahedron, Octahedron, Icosahedron, Cube, and Dodecahedron
What are the names of the five platonic solids?
The tetrahedron, the cube, the octahedron, the dodecahedron and the icosahedron.
What is the collective name of these solids tetrahedron cube octahedron dodecahedron?
Together with icosahedron (20 faces) they are known as the Platonic Solids.
What shape has 4 faces which are congrugent triangles?
A four faced figure is a tetrahedron. If they are all congruent triangles, they are all equilateral triangles and it is a regular tetrahedron - one of the 5 Platonic Solids.
What platonic solid is a pyramid?
The platonic solids are: a tetrahedron, a cube, an octahedron, dodecahedron and icosahedron. A pyramid has a base with triangles attached to it with a common vertex. The platonic solid that is a pyramid is a tetrahedron (a triangular based pyramid).
How do you define platonic solids?
the five regular (same side length and angle measure) solids- dodecahedron, tetrahedron, cube, octahedron, icosahedron
What is the collective name of a cube tetrahedron dodecahedron and a octahedron?
Polygons ( means many sides). They are called solids or polyhedrons; they exist in three dimensions and not two.
What platonic solids is also a cone?
You could classify a regular tetrahedron, which is a platonic sold, as a cone.
How many faces does a polyhydra triangle have?
There are several triangular polyhedra. The simplest is a tetrahedron with 4 faces, but you can have a triangular dipyramid (two tetrahedra stuck together along one face) which has 6 faces. Then there is the icosahedron with 20 faces. The tetrahedron and icosahedron are Platonic solids, but there are many more.
