Special quadrilateral family
Quadrilateral
Kite
Definition
A quadrilateral with exactly two
distinct pairs of adjacent
congruent sides.
Properties





Trapezoid
A quadrilateral with exactly one
pair of parallel sides called bases.



two pairs of adjacent sides
are congruent
diagonals are perpendicular
the long diagonal separates
the kite into two congruent
triangles
the long diagonal bisects the
two angles it intersects
the short diagonal separates
the kite into two noncongruent triangles
two pairs of base angles
formed by one base and the
legs
the non-parallel sides are the
legs
if the legs are congruent the
trapezoid is an isosceles
trapezoid
o each pair of base
angles are congruent
o the diagonals are
congruent
