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

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

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

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

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

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

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 2 yd packages, how many packages must she buy?

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

EX 4: Calculate WX and AB.
