In a trapezoid, which lines were parallel?

• None of the lines

• The diagonal lines

• The top and bottom lines

• The non-adjacent sides

How can you denote that lines are parallel in diagrams?

• By marking them with little lines

• By coloring them the same

• By drawing arrows on them

• By writing 'parallel' next to them
