9.5 Kites and Kite: a quadrilateral with 2 distinct pairs of congruent, consecutive sides

Trapezoids

Properties of Kites

1) 2 pairs of consecutive, congruent sides.

2) Only ONE pair of opposite angles are congruent (between 2 noncongruent sides)

Notebook Paper

Clip b4 p. 471

3) Diagonals are perpendicular

4) exactly ONE diagonal bisects the other

Isosceles Trapezoid: a trapezoid with congruent legs

Properties of Isosceles

Trapezoids

Handout

9.5 Kites and Trapezoids

Extra Theorem for Isosceles Trapezoids Properties of Isosceles Trapezoids

If you know it is a trapezoid (1 pair of sides //)... If EVEN JUST ONE PAIR of base angles are =~ it is an isosceles triangle
