Pyramids that do not have parallel faces are known as irregular or non-regular pyramids. Unlike regular pyramids, where the base is a regular polygon and the triangular faces are congruent, irregular pyramids can have bases of varying shapes and sizes, leading to non-parallel faces. An example of this is a pyramid with a base that is a scalene triangle, where the triangular faces can differ in size and shape.
What else can I help you with?
Are any of a square based pyramids faces have parallel lines?
Yes. A square consists of two pairs of parallel lines!
Does square pyramid have at least one pair of parallel faces?
No, pyramids of any kind will never have any parallel faces. This is because all of the faces, excluding the base, must meet at a single point.
Are Some polyhedrons are neither prisms nor pyramids?
Yes, some polyhedrons are neither prisms nor pyramids. For example, a regular dodecahedron, which has twelve faces that are regular pentagons, does not fit the definitions of a prism (which has two parallel faces that are congruent polygons) or a pyramid (which has a single base and triangular faces meeting at a point). Other examples include the truncated tetrahedron and the icosahedron, which also do not conform to the characteristics of prisms or pyramids.
Is all polyhedrons prism or pyramid?
Not all polyhedrons are prisms or pyramids. A polyhedron is defined as a three-dimensional shape with flat polygonal faces, straight edges, and vertices. While prisms have two parallel faces (bases) connected by rectangular lateral faces, and pyramids have a base and triangular faces that converge at a point, there are other types of polyhedrons, such as irregular polyhedra, that do not fit these definitions. Examples include shapes like the truncated tetrahedron or the dodecahedron, which do not qualify as either prisms or pyramids.
Do pyramids have perpendicular faces?
No.
Do pyramids have parallel faces?
no, the three sides converge at the top. and the bottom does not have an opposite side. Pyramids can be constructed on a square/rectangle base or a triangle base. Faces are parallel or otherwise accordingly

What solid figure has three pairs of parallel parallel faces and all faces are congruent?
A cube has three pairs of parallel faces and all faces are congruent.
Do pyramids have perpendicular faces?
No.
What shape are the faces on a triangular pyramid?
triangle... because pyramids are triangular therefore triangular pyramids have triangle faces
How many parallel faces does a dodecahedron have?

Does a octahedron have any parallel faces or edges?
its has parallel faces and edges
How many parallel faces does an octahedron have?
There are 257 topologically different convex octahedra. Many of these will have no parallel faces. It can have four pairs of parallel faces.
