A picture of a hexagon with one pair of parallel sides would depict a trapezoid. A trapezoid is a quadrilateral with one pair of parallel sides. In this case, the hexagon would have six sides, with two of them being parallel to each other. The other four sides would not be parallel, distinguishing it from a regular hexagon.
It is possible for a hexagon to have one pair of parallel sides. A hexagon can have 0, 1, 2 or 3 pairs of parallel sides, and can have 0, 2, 3, 4, 5, or 6 parallel sides.
a hexagon
Three pairs: all six sides are members of a parallel pair.
A square.
A hexagon with only one pair of parellel sides
It is possible for a hexagon to have one pair of parallel sides. A hexagon can have 0, 1, 2 or 3 pairs of parallel sides, and can have 0, 2, 3, 4, 5, or 6 parallel sides.
a pentagon
a hexagon
A hexagon can have 0, 1, 2 or 3 pairs of parallel sides. A regular hexagon has 3 pairs of parallel sides. A hexagon can also have 2 sets of 3 parallel sides! If you are allowed to count sides in more than one pair, this would be 6 pairs of parallel sides!
Three pairs: all six sides are members of a parallel pair.
An irregular hexagon.
A square.
There is no specific name. For example, if you number the sides of a regular hexagon sequentially from 1 to 6, then sides 1 and 3 are not parallel but there is no specific name for that pair. In the context of the hexagon they do not meet - even if they do so way outside the hexagon. If they do meet up in the context of the shape, then they will be adjacent or intersecting sides.
A hexagon with only one pair of parellel sides
cuz it has 6 sides and each opposite pair will never meet each other when drawn longer.
One pair? If it is one pair of parallel sides, then it is a trapezoid. If it has 2 pairs of parallel sides, then it is a parallelogram.
An isosceles trapezoid must have a pair of parallel sides and a pair of congruent sides
