7. Theorem 6-20
If a quadrilateral is an isosceles trapezoid, then its diagonals are congruent.

8. Midsegment of a Trapezoid
The segment that joins the midpoints of the legs.

9. If a quadrilateral is a trapezoid, then
Theorem 6-21
If a quadrilateral is a trapezoid, then
The midsegment is parallel to the bases
The length of the midsegment is half the sum of the lengths of the bases.
