2.  A trapezoid is a quadrilateral with two parallel sides (called bases) and two non- parallel sides (called legs)

3.  …which is the isosceles trapezoid.  In the isosceles trapezoid, the leg are equal in length and the base angles are congruent.

4.  A line segment connecting the midpoints of the legs of a trapezoid.  The median is parallel to the bases.  Its length is the average of the two bases.

5.  (b 1 +b 2 )/2 * h

6.  A= 100, b 1 = 5, b 2 =15, h=?  A= ?, b 1 = 12x, b 2 =20x, h=9

7.  m=median  A=120, b 1 = 5, b 2 =15, h=?, m= ?  A= 200, b 1 = ?, b 2 =15, h=10, m=?

8.  Use the diagram to help find the values.  A=  b 1 = 5  b 2 =15  h=  m=

9.  Use the diagram to help find the values.  A=  b 1 = 5  b 2 =15  h=  m=
