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 non-congruent 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.

Geometric Figure Made with Kites

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 net of a deltoidal icositetrahedron to cut out and paste together.
	A deltoidal hexecontrahedron is a polyhedron whose faces are kites.
