Here are some more challenges from Mr. Quincey. For each description of a quadrilateral below, say what special type the quadrilateral must be and/or what special type the quadrilateral could be. Look out: Some descriptions may have no “must be”s, and some descriptions may have many “could be”s!  

Try drawing shapes that would fit the descriptions Mr. Quincey gives in parts (a) and (b).

  1. My quadrilateral has two right angles.

    must be: none
    could be: trapezoid, rectangle, or square

  2. The diagonals of my quadrilateral are perpendicular.

    There are no ''must be''s for part (b) either.
