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 square
rectangle
It's impossible for a quadrilateral to have no equal sides and have right angles.
Yes and no. By definition, a quadrilateral is a closed figure with 4 sides. So any square or rectangle will answer your question. However a polygon with 4 sides which are unequal in length will not have 3 right angles.
Quadrilateral
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.

Square
a pentagon
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 square..
Quadrilateral means four sides. Four right angles and four sides is a rectangle and if the sides are equal length it is a square.
A regular quadrilateral is a square. It is a four-sided figure with all sides being the same length and all angles equal (right angles).
A Rhombus had 2 pairs of parallel sides and has NO right angles. :)
