7-142.

MUST BE, COULD BE

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 statements, and some descriptions may have many could be statements! Homework Help ✎

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.
