What is the definition of a trapezoid?

• A. A quadrilateral with one pair of parallel sides
• B. A triangle with one right angle
• C. A polygon with four equal sides
• D. A shape with all sides parallel

Answer: (A)

A trapezoid is defined as a quadrilateral with one pair of parallel sides. This means that among the four sides of the trapezoid, two sides will run parallel to each other while the other two sides do not have to be parallel. This characteristic distinguishes trapezoids from other types of quadrilaterals, specifically parallelograms, which have two pairs of parallel sides. The correct definition emphasizes the unique property of trapezoids that sets them apart in the family of quadrilaterals. It effectively captures the essence of what a trapezoid is in geometric terms, making it fundamental to understanding this figure. Understanding this definition helps students recognize trapezoids in various contexts, including geometry lessons and practical applications in design and architecture.
