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.
