A Rhombus had 2 pairs of parallel sides and has NO 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.
A parallelogram is a geometric quadrilateral with two pairs of parallel sides. The opposite sides and opposite angles are equal in length.
The shape you are looking for is a quadrilateral. If you have a square, all angles MUST be right angles. A parallelogram can also have 4 equal sides in length and parallel sides, but a parallelogram doesn't have right angles.
A square, rectangle, or quadrilateral A square, rectangle, or quadrilateral
It is a rhombus. It is the only equilateral parallelogram other than a square, which conversely has all 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.
A rectangle.
a trapizoid
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
A TRAPEZIUM. Trapezia can be SYMMETRIC or ASSYMETRIC. That is Non-parallel sides can be of the same length or of different lengths/ intersext at different angles to the parallel lines.
A square has 3 sets of parallel sides of equal length AND all the angles are 90 degrees. A rhombus has 2 sets of parallel lines of equal length, but the angles aren't all 90 degrees.
a trapezoid
Rhombus
An isosceles trapezium.
It is a parallelogramIf one of the angles is a right angle (then they all are) and the quadrilateral is a rectangle.If both pairs of sides are equal in length (but none of the angles is a right angle) the quadrilateral is a rhombus.If the sides are equal and one of the angles is a right angle, the quadrilateral is a square.
A quadrilateral with exactly one pair of parallel sides is called a trapezoid (or trapezium in some regions). The parallel sides are referred to as the bases, while the other sides are the legs. Trapezoids can be further classified into isosceles trapezoids if the non-parallel sides are of equal length.
