Sam draws a quadrilateral. it has one pair of parallel sides. what figure did sam draw? show your work

I am sorry but I might not be able to show my work. But the answer is a trapezoid. This is what I did. I looked through my geometry angles, lines and shapes flash cards and saw the trapezoid. It only has one pair of parrelell sides. ( in a regular one it would be the top and bottom) and it has four sides so it is a quadrilateral. And so the answer is a trapezoid. I hope this helped you!
