Kite


Akiteis a differenttype of quadrilateral.It doesnot haveparallelsidesor right angles.Instead,a kite is
definedas a quadrilateralthat has two distinctpairsof adjacentcongruentsides.Unlikeparallelogramsor
otherquadrilaterals,the congruentsidesare adjacent(nextto eachother),not opposite.


Trapezoid


Atrapezoidis a quadrilateralthat has exactlyone pair of parallelsides.Unlikethe parallelogramthat has
two pairs,the trapezoidonly has one. It may or may not containright angles,so the anglesare not a distin-
guishingcharacteristic.Rememberthat parallelogramscannotbe classifiedas trapezoids.A trapezoidis
classifiedas havingexactlyone pair of parallelsides.


IsoscelesTrapezoid


Anisoscelestrapezoidis a specialtype of trapezoid.Like an isoscelestriangle,it has two sidesthat are
congruent.As a trapezoidcan only haveone pair of parallelsides,the parallelsidescannotbe congruent
(becausethis wouldcreatetwosets of parallelsides).Instead,the non-parallelsidesof a trapezoidmust
be congruent.
