Which of the following shapes is defined by opposite sides being parallel and equal in length as a primary property?

Explanation:
Opposite sides parallel is the hallmark of a parallelogram. In a parallelogram, each pair of opposite sides runs in the same direction, so they are parallel, and the geometry also ensures those opposite sides are equal in length. This combination—opposite sides being parallel and equal in length—fits the parallelogram description best. The other shapes are defined by different key properties: a rectangle by four right angles, a rhombus by all sides equal, and a square by all sides equal and all angles right. So the shape described is a parallelogram.
