 Manipulative 1  Kite Created with GeoGebra. 

A kite is a quadrilateral with two sets of
adjacent,
congruent
sides.
Properties of a Kite
 All kites are quadrilaterals.
 The area of a kite is
where p is the length of one diagonal and q is the
length of the other diagonal. See manipulative 1.
 The
diagonals
of a kite are
perpendicular.
 Opposite
vertices
of a kite are congruent.
 An incircle can be inscribed into any convex kite.
 One of the diagonals of a convex kite divides the kite into two
isosceles triangles.
The other diagonal of a convex kite divides the kite into
two congruent triangles.

Construction of the Incircle of a Kite
Step  Diagram  Description 
1   Start with a convex kite. 
2   Construct the angular bisector of one of the angles connecting congruent sides. 
3   Construct the angular bisector of one of the angles connecting noncongruent sides. 
4   Label the intersection of bisectors from steps 2 and 3 as O. 
5   Construct a line through O perpendicular to one of the sides. 
6   Label the intersection of the line constructed in step 5 with the side to which it is perpendicular as P. 
7   Construct a circle with center O and radius OP. 
Table 1 
Image  Description 

This tessellation using kites is called a
deltoidal trihexagonal tiling.
To construct this tessellation, divide each hexagon into six kites by
drawing a segment from the midpoint of each side to the center. Then
tesselate the divided hexagon so that three hexagons share each vertex.


A deltoidal icositetrahedron is a polyhedron whose faces are
kites. Click to print a

A deltoidal hexecontrahedron is a polyhedron whose faces are kites.
