A tetrahedron is a triangular based pyramid that has 4 equilateral triangle faces, 6 edges and 4 vertices.
A cube has three pairs of parallel faces and all faces are congruent.
A solid with six congruent square faces is a cube.
A hexagon
squares.
it is a rectangular prism...
Isosceles TetrahedronA solid with four faces is a tetrahedron. Each of the faces is a triangle. If all the triangles are congruent, you have an isosceles tetrahedron.
A solid with congruent faces is a regular polyhedron, such as a cube or a regular tetrahedron. In a cube, all six faces are identical squares, while in a regular tetrahedron, all four faces are congruent equilateral triangles. These shapes exemplify how congruent faces contribute to the symmetry and uniformity of the solid.
A tetrahedron - ie a triangular pyramid.
A tetrahedron (or triangular pyramid).
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.
The Platonic Solids: Tetrahedron, cube, octahedron, dodecahedron and icosahedron.
It is a tetrahedron pyramid that has 4 faces, 6 edges and 4 vertices.
They don't have names beyond "the faces of the tetrahedron."
In a tetrahedron all the triangles have to be congruent. In a Triangular Pyramid, the lateral faces are all congruent to each other, but not always with the base triangle. Not necessarily. The lateral faces need to be congruent if it is a right pyramid, not otherwise. The apex of the pyramid need not be directly above the centre (however defined) of the base. Think of a triangular pyramid doing an impersonation of the Leaning Tower of Pisa!
No. The faces of a tetrahedron are equilateral triangles, but none of the faces is parallel to another one of the faces -- they could not be parallel, since by the definition of a tetrahedron, all the faces intersect(!) and parallel planes do not intersect.
The faces of a tetrahedron are all triangular polygons. Specifically, a regular tetrahedron has equilateral triangles as its faces, while an irregular tetrahedron can have any type of triangle as its faces, but they will always be triangular in shape. Each tetrahedron has four triangular faces, four vertices, and six edges.
A Cuba has 6 congruent faces
