How can you determine if a quadrilateral is a parallelogram?

• The sum of all angles must be 360 degrees.

• At least one pair of adjacent sides must be equal.

• All sides are equal in length.

• A quadrilateral is a parallelogram if opposite sides are equal, opposite angles are equal, or diagonals bisect each other.

Answer explanation

A quadrilateral is a parallelogram if opposite sides are equal, opposite angles are equal, or diagonals bisect each other. This distinguishes it from other quadrilaterals, making this the correct choice.
