Rhombus and a trapezoid
A trapezoid may have a right angle and a square is also a rhombus, so the kite is the only quadrilateral that can't have a right angle.
A quadrilateral is any shape with four sides; angles can be acute or obtuse. A perfect square is the only quadrilateral with only right angles.
A Rectangle or a square. The word 'rectangle' comes from Latin and means 'Right(Recto) Angles'.

It is a convex quadrilateral, as the remaining angles could be any two angles with a sum of 180 degrees.
Can be a Parallelogram, a Rhombus, A Kite, or a Trapezium. However, A kite may display one right angle, depending on its angular measure. An Asymmetric Trapezium may also display two adjacent right angles. A Symmetric Trapezium does NOT have any right angles. NB A Square has four right angles. A RECTANGLE has four right angles. The word 'Rectangle' is from its Latin base , meaning 'Right(rect) Angles).
Any quadrilateral in which at least one (and therefore at least two) angles are not right angles is not a rectangle. The majority of these do not have a specific name.
