Any even-sided, regular shape will have opposite sides parallel. A square, hexagon, octagon and decagon are just four examples !
Any regular polygon with an even number of sides will have opposite sides that are parallel. For quadrilaterals (4-sided shapes), a trapezoid has one set of opposite sides and a parallelogram (rectangle, square, rhombus) has both sets of opposite sides parallel.

i have a feeling its a rhombus
every parallelogram
rectangle
an perticulogram
hexogon
A parallelogram is a four sided shape where opposite sides are parallel and equal lengths. If you mean that ALL sides are equal lengths, you are looking for a rhombus.
Any shape with at least two straight sides can have opposite parallel and congruent sides. For example, a running track.

A shape that has no pairs of opposite sides parallel is a trapezium (or trapezoid, depending on the region). In a trapezium, only one pair of sides may be parallel, while the other two sides are not. Other irregular polygons, such as pentagons or hexagons, can also have no pairs of opposite sides parallel, depending on their specific configurations.
