A trapezoid has exactly one pair of parallel sides opposite of each other. It is the only quadrilateral with this characteristic.
A quadrilateral with one pair of parallel sides is known to as a trapezoid
A quadrilateral with only one pair of parallel sides is a trapezoid.
trapezoids
Any polygon, other than a triangle, can have one pair of parallel sides.
Just the one pair of different lengths

A quadrilateral with only one pair of parallel sides is a trapezoid.
Both have at least one pair of parallel sides. In a trapezoid the other pair is not whereas in a parallelogram it is.

a trapezoid
A trapezoid is a shape that has one pair of parallel faces, specifically in the case of a trapezoidal prism. This three-dimensional figure has two trapezoidal bases that are parallel, while its lateral faces are rectangular, creating perpendicular edges between the bases and the lateral faces.
At least one pair, or one pair? If it is one pair, then it depends if the shape is regular or irregular.
One shape that has 12 edges is a cube. Any cuboid shape in general like a traditional cube or even an oblong can have 12 edges.
A trapezoid has at least one pair.
