The opposite sides of a trapezoid that are parallel to each other are called bases. The remaining sides of the trapezoid, which intersect at some point if extended, are called the legs of the trapezoid. The top and bottom sides of the trapezoid run parallel to each other, so they are the trapezoid's bases. The other sides of the trapezoid will intersect if extended, so they are the trapezoid's legs. The segment that connects the midpoints of the legs of a trapezoid is called the midsegment.
