4sides
The only polygon that absolutely positively never has any parallel sides is a triangle. Any other shape comprised of four or more straight line segments could have one or more pairs that are parallel.
No. it is the only polygon that can not have parallel lines all though any regular polygon with an odd number of lines will have no parallel lines If three points were in a straight line it could be argued that these formed a triangle with parallel sides, though really it would be just a line; or if we had a triangle with infinite height the sides would be parallel. In any other case, no.
A four-sided polygon with opposite sides parallel could be a square, a rectangle, or a rhombus.If it has one pair of opposite, parallel sides, then it is a trapezoid. If it has two pairs of opposite, parallel sides, then it is a parallelogram.
It takes an infinite number of sides to make a polygon into a circle, but you could still consider a circle to be a limiting state of the polygon, which all polygons approach as the number of sides increase.
Multiply the previous number of segments by 2.

Rhombus
A circle.
It could be a cylinder or a cuboid
a polygon
A trapezium could do that. Moreover, I think any polygon with an even number of sides also could.
A irregular polygon will not have any parallel lines. :)* * * * *Not true. A rhombus is an irregular polygon and it has two pairs of parallel line!An irregular pentagon can have parallel lines.However, a triangle or a conic section cannot.

could be a rhombus and a square and a rectangle.
That could be numerous polygons: a square, a regular hexagon, a regular octagon, a regular dodecagon ... Any regular polygon with an even number of sides could be your answer.
It could be an irregular polygon with 6 or more sides or, if a quadrilateral, it could be a parallelogram.
