A rhombus or a parallelogram
A rectangle is a quadrilateral with opposite sides parallel and congruent and four right angles. If all four sides are congruent, it is a square.
A square or a rectangle
Yes, it can... but does not have to. A parallelogram is a four-sided plane figure with opposite sides parallel. So as long as it has opposite sides that are parallel, it is a parallelogram.
They are 4 sided quadrilaterals and have 4 right angles with a pair of opposite parallel sides but it is not a square.
The picture you are looking for is a parallelogram.
They are alternate angles which are equal in size
A right trapezoid is a four-sided polygon with two right angles and two parallel sides.
A square and a rectangle both fit the description
No. A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel. The opposite angles not congruent.
