A rectangle has 4 sides not the same length and 4 right angles.
It is a rectangle. Just picture it. 4 right angles and 2 sides that are the same length.
Sides cannot be right angles whatever the figure because sides are sides and not angles, the answer you are looking for is a rhombus.
Quadrilateral
a polygon with 4 right angles and 4 sides of the same length
A rectangle
A square has 4 right angles and 4 equal sides.
a rhombus
A shape with opposite sides parallel and of the same length and four right angles is a rectangle.
a parallelogram with four right angles with sides different in length and width is That would be a rectangle. - HistoryDork
You must be talking about a rhombus.In a rhombus, all four sides are congruent, opposite angles are congruent, and opposing sides are parallel. Rectangles, squares, and kites must be rhombi, and rhombi must be parallelograms, quadrilaterals, and polygons.
