7. If the legs of a trapezoid are congruent, then the trapezoid is an isosceles trapezoid.
Thm: Base angles of an
isosceles trapezoid are congruent
Thm : Diagonals of an
isosceles trapezoid are congruent.

8. Median
The _________ of a trapezoid is the segment that joins the midpoints of its legs. Thm : The median of a trapezoid is Parallel to the bases, and its measure is one-half the sum of the measures of the Bases.
