A quadrilateral or a pentagon can have up to 2 pairs of parallel sides.A hexagon or heptagon can have up to 3 pairs of parallel sides.and so on.So, apart from a triangle, any polygon can have two sets of parallel sides.
Each of the eight line segments is perpendicular to 2 line segments. So there are 8 pair in all.
No. A bed is a three dimensional object: it cannot be a single parallel line. However, a bed will susually contain several sets of lines that are parallel.

Trapezoids have exactly one set of parallel sides.A square has two sets of parallel sides, so it simply cannot be a trapezoid.Because a square is a regular polygon with 4 equal sides and 4 equal angles whereas a trapezoid is an irregular 4 sided polygon.
There are more than two: A parallelogram has two sets of parallel line segments which may be of unequal length; A rectangle is a parallelogram that has line segments that meet at right angles; A rhombus has to sets of parallel line segments which are all of the same length; A square is a rhombus which has line segments meeting at right angles, or stated differently a square is a rectangle which has all line segments of the same length.
A regular hexagon has three sets (pairs) of parallel line segments that form it.

A square has two sets of parallel line segments. "Parallel" does not describe a square, however.
A trapezoid has 1 pair of opposite parallel lines of different lengths.

A square is a regular polygon with two sets of parallel sides. A parallelogram is an irregular polygon with one set of parallel sides. A rhombus is an irregular polygon with two sets of parallel sides. A rectangle is an irregular polygon with two sets of parallel sides. *Note - a regular polygon is a shape in which all sides are equal in length and all angles are equal in measurement.
A rectangle.

A parallelogram is a quadrilateral in which each of two sets of opposite sides consists of two parallel lines (or for math purists I should say, parallel line segments).
