A square
A parallelogram with four right angles is a rectangle; if the rectangle also has four equal sides, then it is known as a square.
There are no right angles in a parallelogram. A parallelogram only has right angles if it is a rectangle, in which case it has exactly four.
A parallelogram with no right angles and four congruent sides is a Rhombus.
A parallelogram does not have to be four right angles. A parallelogram is a four sided shape with two parallel lines.
Not all parallelograms have four right angles; however, if a parallelogram does have four right angles, it is specifically classified as a rectangle. In general, all opposite angles in a parallelogram are equal, and adjacent angles are supplementary. Therefore, while rectangles are a type of parallelogram, most parallelograms do not have right angles.
A rhombus is a parallelogram with all four sides congruent to each other with no right angles. A square is a parallelogram with four congruent sides and four right angles.
A rectangle is a parallelogram with four right angles.
it could be a square or a rectangle. its a square if all four sides are congruent, but if not, its a rectangle.

Parallelogram with four right angles and four equal sides is a square.
-- Every quadrilateral has four sides.-- If it has no right angles, then it could be a parallelogram, a rhombus,a kite, a trapezoid, or any non-regular quadrilateral.
