  1. Trapezoids

  2. Trapezoids *They have only one pair of opposite sides that are parallel base leg leg base

  3. B C E F A D The MEDIAN connects the midpoints of the legs

  4. Median Theorem for Trapezoids parallel to each base and its length is the average of the lengths of the bases

  5. EXAMPLE 1 EF is the median of trapezoid ABCD. Find EF. 22 in. A B E F C D 10 in.

  6. EXAMPLE 2 BC is the median of trapezoid MATH. Find MA. A M 15 in. B C T H 22 in.

  7. EXAMPLE 3 BC is the median of trapezoid TRAP. Find TR. T R 19 in. B C P 11 in. A

  8. If the legs are congruent then the trapezoid is ISOSCELES

  9. If a trapezoid is isosceles then each pair of base angles is congruent

  10. If a trapezoid is isosceles then its diagonals are congruent

  11. M A H T EXAMPLE 4 Find the missing angle measures in trapezoid MATH. 60°
