An equilateral hexagon would work. It has more than 2 pairs of parallel sides though. There is no shape with only 2 pairs of parallel sides besides a parallelogram.
A parallelogram, but only if you are counting in base 9.
A trapezoid is not a parallelogram. A trapezoid is a quadrilateral with at least one pair of parallel sides, while a parallelogram is a quadrilateral with two pairs of parallel sides. These two shapes have different properties and cannot be considered the same.
A quadrilateral is a shape with four sides. A parallelogram is a quadrilateral that has two pairs of parallel sides (i.e. the sides opposite each other are parallel). A rectangle, for example, is a parallelogram. A trapezoid, however, is an example of a quadrilateral that is not a parallelogram - it has four sides, but only two of them are parallel to each other.
a square! * * * * * That is true only as a very special case.
A trapezoid has only one pair of parallel opposite sides; in a parallelogram, both pairs are parallel.
It only has 1 pair of parallel sides. a parallelogram has at least 2 pairs of parallel sides.
No. It's only a parallelogram if both pairs of opposite sides are parallel.
no only one side is parallel
A parallelogram has two pairs of parallel sides, whereas a trapezoid has only one pair.
A parallelogram has two pairs of parallel sides, a trapezium has only one such pair.
A trapezoid has only one pair of parallel lines so it cannot be a parallelogram which must have two pairs of parallel lines.
