A parallelogram, rhombus, or diamond, because a square would have FOUR right angles.
A rectangle. If there are equal adjacent sides it's a square.It is a square or a rectangle both of which are 4 sided quadrilaterals
A quarangle is a four sided shape so if it's a square it could have four right angles
A four-sided polygon with all sides equal and no right angles would be a rhombus. A rhombus consists of two acute angles and to obtuse angles.
This is false. A rectangle has that property as well. Squares and rectangles have 4 sides and 4 right angles (90 degrees). The difference is that a square has 4 equal sides, while a rectangle does not.
rectangle, square
No because a rectangle also has 4 right angles.
No. A trapezoid is any four sided shape which has at least two parallel sides. If it is four sided, cannot have exactly four right angles.
An irregular heptagon.
No. For example a parallelogram does not have any right angles. The internal angles of all four sided shapes will always equal 360 degrees, but do not necessarily have to include right angles.
A parallelogram does not have to be four right angles. A parallelogram is a four sided shape with two parallel lines.
No because the interior angles of a four sided shape can't exceed 360 degrees.
A right trapezium or an irregular quadrilateral.
If you mean shape there is no such shape. if a 4 sided shape has 2 right angles it MUST be either a square or a rectangle, in which case there are actually 4 right angles and 2 pairs of parallel sides. =)

A general quadrilateral. No special name.
