### Theory:

A quadrilateral with two pairs of equal adjacent sides and unequal opposite sides is called a kite.
Now we are going to define a kite $$ABCD$$ is a quadrilateral having two pairs of equal adjacent sides and unequal opposite sides.

Thus, if $$ABCD$$ is a kite, then $$AB = AD$$ and $$BC = CD$$.
In a kite, the following properties are true:
1. The sum of all the four angles of the kite is equal to $$360°$$.
2. A kite has two pairs of equal adjacent sides.
3. A kite has unequal opposite sides.
4. The diagonals of kite perpendicular bisect of each other.
5. One of the diagonals bisects the other diagonal.
6. In the figure, $$∠B =∠D$$ but $$∠A $\ne$ ∠C$$.
