1. What do you remember? List all the quadrilaterals that have:
A) all sides congruent
B) opposite sides congruent
C) diagonals perpendicular
D) diagonals congruent
E) consecutive angles supplementary
F) all angles are right angles
G) diagonals bisect the opposite angles

2. 6-6 Trapezoids and Kites
Rigor: Correctly identify and use properties of trapezoids and kites
Relevance: Design

3. Trapezoids & Isosceles Trapezoids
Definition of a Trapezoid – a quadrilateral with exactly 1 pair of parallel sides
Definition of an Isosceles Trapezoid – a trapezoid with congruent legs

4. Isosceles Trapezoid Theorems
Theorem – each pair of base angles of an isosceles trapezoid is congruent
Theorem – the diagonals of an isosceles trapezoid are congruent.

5. Kites
Definition – A quadrilateral with 2 pairs of consecutive sides congruent and no opposite sides congruent
Theorem – The diagonals of a kite are ┴.
Theorem – One diagonal of a kite is a line of symmetry (bisects the kite).

6. EX 1: Trapezoids a) Calculate the measure of each angle of the isosceles trapezoid.
b) What is the length of each diagonal if QS =(7x – 5)cm, & RP =(3x +11)cm

7. EX 2: For kite KLMN, calculate the measures of the numbered angles.

8. EX 3: Building a Kite
Ellie is using a pattern to make a kite to fly outside. To finish the kite, she is putting a binding around the outer edge What is the perimeter of the kite (round to the nearest hundredth)? If the binding is sold in 2yd packages, how many packages must she buy?

9. Trapezoid Midsegment Theorem
The midsegment of a trapezoid is the segment connecting the midpoints of the legs
Theorem – The midsegment of a trapezoid is parallel to each base, and its length is ½ the sum of the lengths of the bases.

10. EX 4: Calculate WX and AB.
