Which quadrilateral has one pair of parallel sides, but is not a parallelogram? (1 point)

The quadrilateral you're thinking of is a trapezoid! This fascinating shape features one pair of opposite sides that run parallel to each other, while the other two sides can take on various angles and lengths, which means it’s not a parallelogram. This unique characteristic gives trapezoids a wide variety of forms, such as isosceles trapezoids, where the non-parallel sides are equal in length. Trapezoids have interesting applications in real life too! For instance, they can be found in architectural designs where unique roof shapes are necessary, or in certain furniture designs where aesthetics play a huge role. Additionally, trapezoidal shapes can appear in fields such as engineering and construction to optimize space and materials.
