A quadrilateral with exactly one pair of parallel sides Trapezoid A quadrilateral with exactly one pair of parallel sides

Parts of a Trapezoid Base Leg Leg Base Angle Base Base Angle

A trapezoid with congruent legs and congruent base angles. Isosceles Trapezoid A trapezoid with congruent legs and congruent base angles.

Theorem 6-19 If a quadrilateral is an isosceles trapezoid, then each par of base angles is congruent.

Look at Problems 1 and 2 Try the Got It Problems for those examples. Turn to Page 390 Look at Problems 1 and 2 Try the Got It Problems for those examples.

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

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

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.

Kite Quadrilateral with two pairs of consecutive sides congruent and no opposite sides congruent.

If a quadrilateral is a kite, then its diagonals are perpendicular. Theorem 6-22 If a quadrilateral is a kite, then its diagonals are perpendicular.
