"Tetra" is the Greek word for "four," and the word "hedron" translates to "face." So a tetrahedron has four faces, all of which are triangles.
A cantellated regular tetrahedron, in the form of a regular cuboctahedron, has 14 faces (8 triangular, and 6 square), 24 edges and 12 vertices.
A tetrahedron is a triangular based pyramid that has 4 faces, 6 edges and 4 vertices
A Tetrahedron. The most common form of a tetrahedron is called a regular tetrahedron, or a pyramid
There are four number of faces in a tetrahedron.
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 tetrahedron has 4 faces. A "regular tetrahedron" has an equilateral triangular base with three equilateral triangles as sides coming up from it.
In geometry, a tetrahedron is a solid with four faces, which is a triangular pyramid (don't forget the base-face), and a regular tetrahedron has (4) faces that are equilateral triangles.

No and Yes A regular tetrahedron does not have any faces that are perpendicular to each other. (Regular in this sense means all edges are equally long - all faces are equilateral triangles)You can construct a irregular tetrahedron with two or three perpencdicular faces. To make such a tetrahedron with three faces perpendicular, simply cut the corner of a cube.
Yes. A tetrahedron is a closed 3-d shape with 4 triangular faces. In a regular polygon, each of these is an equilateral triangle.
A tetrahedron has 4 faces.
