Exercise 2 Page 499

What conditions must a quadrilateral satisfy to be a parallelogram?

No.

Practice makes perfect
To prove that a quadrilateral is a parallelogram, it is enough to show that one of the following conditions is satisfied.
  • Both pairs of opposite sides are parallel.
  • Both pairs of opposite sides are congruent.
  • Both pairs of opposite angles are congruent.
  • The diagonals bisect each other.
  • A pair of opposite sides is both parallel and congruent.

Let's analyze the given quadrilateral.

One of the diagonals is bisected, but the other one is not. Therefore, it is not a parallelogram.
