A shape with straight lines where opposite sides are equal and parallel is called what?

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

Answer: (B)

A shape that has straight lines with opposite sides that are both equal in length and parallel is referred to as a parallelogram. This definition is grounded in the properties that characterize parallelograms, which include not only opposite sides being equal and parallel but also opposite angles being equal, and adjacent angles being supplementary. This makes parallelograms a specific type of quadrilateral, as all parallelograms are indeed quadrilaterals (a four-sided shape). However, the defining feature of equal and parallel opposite sides distinctly identifies it as a parallelogram rather than a more general quadrilateral. Moreover, while a trapezoid has at least one pair of parallel sides, it does not require both pairs of opposite sides to be parallel. A rhombus is a special type of parallelogram where all four sides are equal in length, but it still fits within the category of parallelograms defined by the parallel and equal sides. Therefore, the best answer specifically highlighting the properties of equal and parallel opposite sides is the parallelogram.
