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.

A rectangle.

quadrilateral--a four-sided figure, any length sides, any angles trapezoid--one pair of parallel sides, any length sides, any angles parallelogram--two pairs of parallel sides, opposite sides congruent, opposite angles congruent rectangle--two pairs of parallel sides, opposite sides congruent, all angles are right angles (90 degrees) rhombus--two pairs of parallel sides, all sides congruent, opposite angles congruent square--two pairs of parallel sides, all sides congruetn, all angles are right angles (90 degrees)

If both pairs of opposite sides are the same length, and both pairs of opposite angles are the same, the quadrilateral is a parallelogram (rhombus, rectangle, or square).

A rhombus is a simple quadrilateral with all its sides of equal length. As a result,its opposite sides are parallel,its opposite angles are equal,its adjacent angles are supplementary, andits diagonals bisect each other at right angles.

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.

If both pairs of opposite sides are the same length, and both pairs of opposite angles are the same, the quadrilateral is a parallelogram (rhombus, rectangle, or square).

A quadrilateral containing 4 right angles is called a rectangle. opposite sides will necessarily be parallel and equal in length. In the special case where all four sides are equal in length, the figure will be a square.

The practical answer is a parallelogram, which has two sets of parallel opposite sides and two sets of equal opposite angles. This includes rhombi, rectangles, and squares.A trapezoid (trapezium) has one set of parallel opposite sides that are not equal, but may have non-parallel opposite sides equal in length (isosceles trapezoid).
