Question
There are five ways to confirm that a quadrilateral is a parallelogram.
If both pairs of opposite sides are parallel, then the quadrilateral is a parallelogram.
If both pairs of opposite sides are congruent, then the quadrilateral is a parallelogram.
If both pairs of opposite angles are congruent, then the quadrilateral is a parallelogram.
If the diagonals bisect each other, then the quadrilateral is a parallelogram.
If one pair of sides is both congruent and parallel, then the quadrilateral is a parallelogram.

To complete the statements based on the properties of a parallelogram, we can fill in the information as follows:
1. If \( AB \cong CD \), and \( BC \cong AD \), then ABCD is a parallelogram.
2. If \( m\angle A + m\angle B = 180^\circ \), and \( m\angle C + m\angle D = 180^\circ \), then ABCD is a parallelogram.
3. If \( \angle A \cong \angle C \), and \( \angle B \cong \angle D \), then ABCD is a parallelogram.
4. If \( AE \cong BE \), and \( DE \cong CE \), then ABCD is a parallelogram (assuming AE and BE are segments that cut the diagonal of the quadrilateral).
5. If \( BC \cong AD \), and \( BC \parallel AD \), then ABCD is a parallelogram.
6. If \( CD \cong AB \), and \( CD \parallel AB \), then ABCD is a parallelogram.
Just replace \( AB \), \( CD \), \( BC \), \( AD \), or their corresponding angle notations with any specified values from your diagram if needed.
