opposite sides parallel;

exactly 1 pair of opposite

6. Stretch Your Thinking Suppose you drew a diagonal in
each of the following quadrilaterals: rectangle, trapezoid,
parallelogram. In which figures do triangles with the
same size and shape form? In which figures do triangles
with a different size and shape form? Explain.
Possible explanation: triangles with the same size
and shape form only in the rectangle and parallelogram,
because both pairs of opposite sides are parallel and
equal in length. The trapezoid, which has only one
pair of opposite sides parallel, would form triangles
with a different size and shape.
