rhombus
trapezoid
A square has 2 pairs of opposite parallel sides
A trapezoid is a quadrilateral (meaning it has 4 sides) with 1 pair of parallel sides (meaning only 1 side is parallel to another on the figure).
A trapezoid has one pair of parallel sides. They are opposite parallel lines of different lengths.
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!
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.
There are two pairs of parallel sides in a rectangle - 1 pair of lengths, and 1 pair of widths.Therefore, 4 parallel sides!
It has 2 parallel sides.
A trapezoid has only 1 pair of opposite parallel sides of different lengths.
It is a trapezoid that has only 1 pair of parallel sides of different lengths
1 pair of parallel sides mean 1 pair of non-intersecting lines for example, squares, their lines don't touch when they up or down.
Squares, rectangles, parallelograms and rhombuses have 2 pairs of parallel sides. The trapezoid has only 1 pair of parallel sides.
An isosceles trapezium.
a trapezoid is the only quadrilateral that has exactly 1 pair f parallel sides.
Any shape wit four of more sides can have one pair of parallel sides.
A circle intersected by a pair of parallel lines.
