Trapezoid

TRAPEZOID: A trapezoid is a quadrilateral having two parallel sides called bases. SCALENE, ISOSCELES, AND RIGHT TRAPEZOID: MEDIAN OF A TRAPEZOID (Midline or Midsegment):  Segment joining the midpoints of the two legs. The median is parallel to the bases and equal to one half of the sum of the bases. MIDPOINTS OF THE DIAGONALS:  The segment joining the midpoints of the two diagonals is parallel to the bases and equal to one half of the difference of the bases.
