Does a tetrahedron have 1 pair of parallel faces?
no
Does a triangular prism have 3 pairs of parallel faces?
No. it could only have one pair of parallel faces. The cross section is triangular.
What 3d shape has 1 pair of parallel faces?
A prism.
What shape has at least one pair of parallel sides?
A trapezoid has at least one pair.
Does a trapezoid have at least one pair of parallel sides?
Not exactly. A trapezoid has exactly one pair of parallel sides -- no more and no less.
What is a polyhedron with exacly one pair of parallel faces?
trapezium
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).
What are pairs parallel faces?
In a polyhedron - a 3-dimensional object - a pair of parallel faces are two faces which lie in planes that are parallel to each other.Parallel faces need not be congruent. For example, consider a pyramid whose top is sliced off by a plane parallel to it base. The flat top and the base will be parallel faces but will not be congruent.
Which figure could never have at least one pair of parallel faces?
A triangle couldn't.
Does a octagonal prism have parallel faces?
Usually, a pair of parallel bases and four pairs of parallel lateral faces.
Does a tetrahedron have 1 pair of parallel faces?
no
A tetrahedron has one pair of parallel faces?
No.
Does a rhombus have four parallel sides?
yeah it does * * * * * No, it does not. It has two pairs of parallel sides. One pair of parallel sides faces in one direction and the other pair of parallel sides faces in another direction.
Does square pyramid have at least one pair of parallel faces?
NO!!!! The base is square. From the base there are four triangular faces that come to a point. . By the fact that the four faces come to a point, then no face is parallel.
What figure has 6 facesall of the faces are congruent with 3 pair of faces that are parallel?
A cube.
Does a triangular prism have 3 pairs of parallel faces?
No. it could only have one pair of parallel faces. The cross section is triangular.
How many pairs of parallel faces has a pentagonal prism?
I think just the 2 end faces will be parallel, so the answer is 1 pair
