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.
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.
No because the interior angles of a four sided shape can't exceed 360 degrees.
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. =)
square
You can make a four sided shape with 3 right angles, but it must have another right angle, too. So technically, yes.
No because a rectangle also has 4 right angles.

An irregular heptagon.

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.

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 general quadrilateral. No special name.
