A parallelogram with no right angles and four congruent sides is a Rhombus.
It is a rectangle unless all sides are congruent, in which event it is a square.
A square is the parallelogram that has all sides congruent. A square also has four angles that are all right angles.

No. If the diagonals of a parallelogram are congruent then it must be a rectangle (or square).
A square is the parallelogram that has all sides congruent. A square also has four angles that are all right angles.
A parallelogram with 4 equal right angles is a rectangle.
It is a rectangle which is technically a parallelogram
a rhombus
Rectangle.
4 right angles, by definition, are four angles of the same measure, and therefore must be congruent angles.
No, a quadrilateral with congruent diagonals but no right angles is not necessarily a parallelogram. In order for a quadrilateral to be classified as a parallelogram, it must have both pairs of opposite sides parallel. The property of having congruent diagonals does not guarantee that the sides are parallel, so the quadrilateral may not be a parallelogram.
