Investigation 2: Special Quadrilaterals

Sketch 1: Parallelograms can be constructed using any of the definitions of their properties:

- A quadrilateral with two pair of opposite sides congruent
- A quadrilateral with two pair of opposite sides parallel
- A quadrilateral with one pair of opposite sides congruent and parallel
- A quadrilateral with two diagonals that bisect each other
- A quadrilateral with adjacent angles that are supplementary

Which of these do you think was used to create the parallelogram shown below?

**Sketch 3: How was this trapezoid constructed? Are all kites considered parallelograms? Why or why not?**
