1. Geometry Section 8.5 Use Properties of Trapezoids and Kites

2. Trapezoid Quadrilateral with exactly one pair of parallel sides (bases) If the legs of a trapezoid are congruent, then it is an isosceles trapezoid leg base Base angles

3. Isosceles Trapezoid Theorems If a trapezoid is isosceles, then each pair of base angles is congruent

4. If a trapezoid has a pair of congruent base angles, then it is and isosceles trapezoid.

5. A trapezoid is isosceles iff its diagonals are congruent.

6. Midsegment of a trapezoid The segment that connects the midpoints of its legs

7. Midsegment Theorem for Trapezoids The midsegment of a trapezoid is parallel to each base and its length is one half the sum of the lengths of the bases

8. Kite A quadrilateral that has two pairs of consecutive congruent sides, but opposite sides are not congruent

9. Kite Diagonal Theorem If a quadrilateral is a kite, then its diagonals are perpendicular

10. Theorem If a quadrilateral is a kite, then exactly one pair of opposite angles are congruent
