A. A quadrilateral that has diagonals that bisect each other.
B. A quadrilateral that has diagonals that do not bisect each other.
C. A quadrilateral that has opposite sides that are both congruent and parallel.
D. none of the above

Answer 1

The diagonals cannot both bisect and NOT bisect so we know it is either A or B.
It is in fact true that the diagonals of a parallelogram bisect each other.
LETTER B is false.

Answer 2

Answer: B. A quadrilateral that has diagonals that do not bisect each other.

Explanation:

• A parallelogram is a quadrilateral whose opposite sides are equal or congruent and parallel. Also, the opposite sides in parallelogram are equal or congruent and the sum of two adjacent angles is 180 degrees.The diagonals of parallelogram bisect each other.

Therefore by the properties of parallelogram the choice that does NOT describe a parallelogram is " A quadrilateral that has diagonals that do not bisect each other.".
