7-121.
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”s, and some descriptions may have many “could be”s! Homework Help ✎
“My quadrilateral has two right angles.”
“The diagonals of my quadrilateral are perpendicular.”
Try drawing shapes that would fit the descriptions Mr. Quincey gives in parts (a) and (b).
must be: none
could be: trapezoid, rectangle, or square
There are no ''must be''s for part (b) either.
