Understanding Parallelograms

Which of the following is NOT a property of a parallelogram?

• Opposite sides are parallel.

• Diagonals bisect each other.

• All angles are right angles.

• Opposite angles are congruent.

How do you indicate that two sides of a parallelogram are parallel in a diagram?

• By drawing a line through them.

• By marking them with arrows.

• By coloring them the same.

• By labeling them with letters.
