A pentagon has 0, but if you mean a pentahedron, then it depends on how you build it.
a pentagon has no parallel sides
A pentagon has no parallel sides.
A dodecahedron has 0 parallel faces
how many faces does a pentagon prism have
As a regular 5 sided pentagon it has no parallel sides but as an irregular pentagon it can be shaped to have parallel sides.
A pentagon has no parallel lines.
a pentagon has no parallel sides
It depends on the pentagon. If it is regular, then there are no parallel sides.
A regular pentagon has no parallel lines, but you can create an irregular pentagon with one pair of parallel lines if you make a traditional 'house' shape with parallel 'walls'.
A regular pentagon has no parallel lines.
A regular pentagon has no parallel lines, but you can create an irregular pentagon with one pair of parallel lines if you make a traditional 'house' shape with parallel 'walls'.
6 faces
There are 257 topologically different convex octahedra. Many of these will have no parallel faces. It can have four pairs of parallel faces.
A pentagon has no parallel sides.
A dodecahedron has 0 parallel faces
None normally in a regular 5 sided pentagon but it is possible to construct an irregular pentagon with a pair of parallel sides.
there are 5 sides
