Definition:
A quadrilateral with exactly one pair of parallel sides.
The parallel sides are called bases and the non-parallel sides are called legs.

Median of a Trapezoid
The median of a trapezoid is the segment that joins the midpoints of the legs.
The median of a trapezoid is parallel to the bases, and its measure is one-half the sum of the measures of the bases.
