Properties of Quadrilaterals

Is the quadrilateral a parallelogram?

• Yes; one pair of opposite sides are parallel

• Yes; one pair of opposite sides are congruent

• Yes; one pair of opposite sides are parallel and congruent

• No; only one pair of sides are parallel

• No; only one pair of sides are congruent

Determine if the quadrilateral is a parallelogram and justify.

• Is a parallelogram because, opposite sides parallel

• Is a parallelogram because, opposite sides congruent

• Is a parallelogram because, opposite angles congruent

• Is a parallelogram because, one set of sides is parallel and congruent

• Not a parallelogram.
