What else can I help you with?
Is it true that a polygedron has 4 faces?
If you mean a polyhedron then it is true that it can have 4 or more faces
What is the least number of faces that a polyhedron can have?
4
What polyhedron have some a face but no edges and no vertices?
A polyhedron must have at least 4 faces, at least 4 vertices and at least 6 edges.
How many faces and edges does a 3d polyhedron have?
The only thing that can be said that there must be at least 4 faces and at least 6 edges and that the polyhedron must satisfy the Euler criterion which requires that: Faces + Vertices = Edges + 2.
Is the minimum number of faces for a polyhedron is 4?
Yes, the minimum number of faces for a polyhedron is 4. The simplest example is the tetrahedron, which has four triangular faces. A polyhedron must have at least four faces to enclose a three-dimensional space, as three faces would only form a triangular shape without volume.
What is the least amount of edges that a polyhedron may have?
6 edges 4 faces and 4 verticies
How many faces does a 3d polygon have?
The 3-d equivalent of a polygon is called a polyhedron. A polyhedron can have 4 or more faces. Cutting off a section of the polyhedron near a vertex adds another face. And it adds at least two more vertices (at least three new, but one lost), so you can keep adding faces.
What is a polyhedron with 4 faces?
A polyhedron is a 2 dimensional object. To have fasce it would have to be at least 3 dimensional. If you want to know what is a polyhedron with 4 sides, it's a quadrilateral THAT'S NOT QUITE RIGHT - actually it's completely false. Sorry, Ratty, a polyhedron is a 3 dimensional figure. Polygon refers to 2 dimensional figures. A pyramid with a triangular base is a polyhedron with 4 faces.
What is a polyhedron with five faces and a square base called?
A polyhedron can have any number of faces 4 or higher.
What is a polyhedron with 4 faces called?
Tetrahedron
Why does not a tetraheron have one pair of parallel faces?
Each face of a polyhedron is a polygon which has at least three straight sides; all the polygons of the polyhedron join along one of their sides to another polygon to form the edges of the polyhedron.Now consider when you have two parallel faces of a polyhedron:They do not meet (as they are parallel) and so have no side in common to form an edge of the polyhedron;There must be at least three sides to each polygon which means there must be at least three more polygons to join the two faces together (one for each side of the parallel faces);Thus there are at least 2 + 3 = 5 faces to the polyhedron, ie the polyhedron has 5 or more faces.A tetrahedron has 4 faces which is less than 5 faces.Thus two of the faces of a tetrahedron cannot be parallel.The smallest polyhedron which can have a pair of parallel faces is a pentahedron with two triangular parallel faces and three quadrilateral faces joining them (for example a tetrahedron with one corner cut off by a plane parallel to the opposite face).
Can a polyhedron have 4 triangles for its faces?
Yes: the tetrahedron.
