A quadrilateral with exactly one pair of parallel sides is called?

• A. Parallelogram
• B. Trapezoid
• C. Rhombus
• D. Quadrilateral

Answer: (B)

Think about how many pairs of opposite sides run parallel. If a four-sided figure has exactly one pair of sides that are parallel, the shape is called a trapezoid. A parallelogram has two pairs of opposite sides that are parallel, so it does not fit the description of having exactly one parallel pair. A rhombus is a special kind of parallelogram with all sides equal, which also means two pairs of parallel sides. A general quadrilateral could have zero, one, or two pairs of parallel sides, but the phrase “exactly one pair” points to a trapezoid. So the correct term is trapezoid.
