A square and a rhombus
A square is an example of four sided figures with the opposite sides parallel. While all sides have one side that is parallel to the opposing side, the sides are all other parallel to each other. Mathmaticaly speaking each side of the square has one parallel side opposing it and an orthogonal side at each of its ends. The square shares this property with other rectangles
Regular polygons with even sides if there are 6 or more of them; selected irregular polygons with seven or more odd numbers of sides.
Rectangles and squares, sometimes rhombuses and parallelograms are figures that match your description.
A hexagon (6 sides) has three sets of parallel sides.
A quadrilateral with two parallel sides is a trapezoid.

A square and a rhombus
If the shape (a quadrilateral) has only 2 parallel sides, it is a trapezoid (UK trapezium).A shape with four sides and two sets of parallel sides is a parallelogram (rectangle, square, rhomboid, rhombus) because these figures have four sides and two sets of parallel sides.
Lots of figures don't.
you sure you don't mean parallelogram which has 2 pairs of parallel sides? This is too vague?
Any regular polygons with an even number of sides can have opposite sides equal and parallel.For quadrilaterals, if any two sides are equal and parallel, the other two sides must also be equal and parallel, and it is a parallelogram (square or rhombus). If the equal sides are not parallel, the figure is a trapezoid (UK trapezium).
NO!!!! Parallelogram : Two pairs of parallel lines ; The each pair of parallel lines is the same length. Trapezium ; One pair of parallel lines, that are not the same length. The other two sides can be the same length , but not parallel. Both figures/shapes are quadrilaterals.

* Both are four sided figures,so both are quadrilaterals. * In trapezium, one pair of opposite sides are parallel,so as in parallelogram its opposite sides are parallel. *both have at least 2 parallel sides
no. a triangle is not a parallelogram. First of all, a parallelogram should be a quadrilateral, and quadrilateral forms are figures which has four sides. secondly' a parallelogram should have two pairs of parallel sides. a triangle doesn't even have a pair of parallel sides.
