What is a quadrilateral called that has opposite sides that are parallel?

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

Answer: (C)

A quadrilateral with opposite sides that are parallel is specifically classified as a parallelogram. This definition holds true for all quadrilaterals in this category, which includes rectangles and rhombuses as special types of parallelograms. In a parallelogram, not only are the opposite sides parallel, but they are also equal in length, and the opposite angles are equal as well. Understanding this definition helps to clarify why parallelogram is the correct answer. While a rectangle and a rhombus also have pairs of parallel sides, they have additional specific properties: a rectangle has four right angles, and a rhombus has sides of equal length. A trapezoid, on the other hand, only has one pair of parallel sides, which disqualifies it from being a parallelogram. Thus, the unique characteristic of having both pairs of opposite sides that are parallel makes parallelogram the best answer for this question.
