Sides cannot be right angles whatever the figure because sides are sides and not angles, the answer you are looking for is a rhombus.
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.
It may have no right angles, and certainly no parallel sides.
A rectangle has two right angles and parcel sides
It is a rhombus that has 4 equal sides but no right angles.
You don't tell us enough information. In a square, there are four sides and four angles. The sides are all equal and the angles are all right angles. In a rectangle, there are four sides and four angles The opposite sides are equal and the angles are all right angles. There is no other shape in which all angles are right angles.
circle
A right trapezoid can have no congruent sides and two right angles.
False - and false ! Not ALL angles are right-angles - and a triangle has THREE sides !

Rhombus has 4 equal sides and no right angles
A RECTANGLE has 4 sides and 4 right angles.
It may have no right angles, and certainly no parallel sides.
A regular pentagon.
No sides perpendicular means no right angles. A rhombus is a quadrilateral with no right angles so no sides perpendicular.
