A rectangle. The opposite sides at least must be equal if all four angles are 90o.
A polygon with 4 sides has 4 angles. All polyhedra have at least 4 vertices so I cannot think of any shape that meets the requirements.
A square has to have all 4 right angles, by definition
Quadrilateral
False because it depends on what type of a 4 sided quadrilateral it as for example a square has 4 right angles whereas rhombus has no corner right angles.

No. Except for the case of a square (a special case of rhombus), a rhombus will have 2 congruent acute angles, and 2 congruent obtuse angles. The square has 4 right angles. In fact, every quadrilateral will have either all 4 angles equal to right angle (square and rectangle), or will have at least 1 obtuse angle (also at least 1 acute).
Yes. 4 sides 4 angles. All 90%.

As trapezoid is a quadrilateral. All quadrilaterals have 4 angles along with 4 sides
4 corners 4 angles Angles add up to 90' All angles are right angles Has 4 lines of symmetry
All 4 angles are 90 degree angles.
Yes, the 4 inside angles are right angles
It is a RECTANGLE
