  1. Trapezoids Section 6-6

  2. trapezoid – a quadrilateral with exactly one pair of parallel sides The parallel sides are called bases. The nonparallel sides are called legs. base leg leg base

  3. isosceles trapezoid – a trapezoid that has congruent legs

  4. Thms. 8-18 & 8-19 • Both pairs of base angles of an isosceles trapezoid are congruent. • The diagonals of an isosceles trapezoid are congruent. B A AC BD D C

  5. The median of a trapezoid is the segment that joins the midpoints of its legs.

  6. Theorem 8-20 • The median of a trapezoid is parallel to the bases, and its measure is one-half the sum of the measures of the bases.
