A parallelogram. Opposite sides are parallel and congruent.parallelogram is a quadrilateral with two sets of parallel sides. The opposite sides of a parallelogram are of equal length, and the opposite angles of a parallelogram are congruent. The three-dimensional counterpart of a parallelogram is a parallelepiped.Parallelogram - A quadrilateral whose opposite sides are parallel
A quadrilateral (four sided figure) with opposite sides parallel and equal length see: http://dictionary.die.net/parallelogram
rhombus
A [generic] rectangle is a quadrilateral that has two pairs of opposite sides parallel and equal in length, along with 4 right angles.

A parallelogram.
A parallelogram.
rhombus. The rhombus is a quadrilateral with all sides equal in length. It is also a parallelogram, so opposite sides are parallel and equal in length, and opposite angles are equal.
That quadrilateral is known as a 'parallelogram'.
a square and a rhombus share these attributes
A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length, and opposite angles that are equal. Two ways to describe a parallelogram could be as a shape with opposite sides that are both parallel and equal in length, or as a shape with opposite angles that are equal.
Yes, sides are equal in length as well.
A rectangle.
A quadrilateral with 4 right angles and opposite sides that are parallel can be either a rectangle if the adjacent sides are of different length or a square if the adjacent sides are of the same length.
Quadrilaterals that have parallel opposite sides (assuming that each side is parallel to its opposite): A parallelogram A rectangle A square (really a rectangle with all sides equal in length)
A parallelogram is a geometric quadrilateral with two pairs of parallel sides. The opposite sides and opposite angles are equal in length.
A quadrilateral is any plane figure bounded by four straight lines. Within this definition are special shapes. The Parallelogram : has both pairs of opposite sides parallel (and opposite sides are equal in length). The Rhombus : is a parallelogram with all its sides of equal length. The Rectangle : is a parallelogram with each of its vertex angles equal to 90° (and opposite sides are of equal length). The Square : is a rectangle with all its sides of equal length. The Trapezium : is a quadrilateral with only one pair of parallel sides - which are NOT of equal length. The Isosceles Trapezium : is a trapezium with its two non parallel sides equal in length. The Kite : is a quadrilateral with two pairs of adjacent sides equal in length
