Kites and trapezoids are quadrilaterals that do not fall under the category of parallelograms.
A kiteis a quadrilateral with exactly two pairs of congruent consecutive sides. • Kite Properties: • Diagonals are perpendicular. • Only the pair of non-vertex angles are congruent. • Diagonals only bisect the vertex angles. • Only the diagonal through the non-vertex angles is bisected.
Lucy is framing a kite with wooden dowels. She uses two dowels that measure 18 cm, one dowel that measures 30 cm, and two dowels that measure 27 cm. To complete the kite, she needs a dowel to place along . She has a dowel that is 36 cm long. About how much wood will she have left after cutting the last dowel?
In kite ABCD, mDAB = 54°, and mCDF = 52°. • Find mFDA. • Find mABC. • 3. Find mBCD.
In kite PQRS, mPQR= 78°, and mTRS= 59°. • Find mQRT. • 2. Find mQPS. • Find mPSR.
A trapezoidis a quadrilateral with exactly one pair of parallel sides. • Each of the parallel sides is called a base. • The nonparallel sides are called legs. • Base anglesof a trapezoid are two consecutive angles whose common side is a base.
Isosceles Trapezoid • The bases are parallel. • The legs are congruent. • Both pairs of base angles are congruent. • Leg angles add up to 180 degrees. • The diagonals are congruent. • Diagonals do not bisect each other.
