In a parallelogram, opposite sides are what?

In a parallelogram, opposite sides are what?

• A. Opposite sides are parallel
• B. All sides are equal
• C. Diagonals are perpendicular
• D. Opposite angles are supplementary

Answer: (A)

In a parallelogram, opposite sides are parallel. This means each pair of opposite sides runs in the same direction and would never meet, which is the defining property of a parallelogram. You can also recall that opposite sides are equal in length, and the diagonals bisect each other. Diagonals are not generally perpendicular, and opposite angles are equal (not supplementary). So the essential description of opposite sides is that they are parallel.
