Introduction:
A quadrilateral is a two-dimensional figure created by connecting four segments endpoint to endpoint with each segment intersecting exactly two others. It also has four sides and four angles. Sum of interior angle of any polygon is (n-2) 180o. Here quadrilateral has four sides so interior angle is (4-2)180o = 360o. Exterior angle of any polygon is 360o so the exterior angle of a quadrilateral is 360 degree.

The opposite angles of a parallelogram are equal
The opposite sides of a parallelogram are parallel
Kite:
The name of this shape is called as kite
The adjacent sides of a kite are equal, so it has two pairs of equal sides.
The diagonal angles of a kite is equal to 90o
One pair of opposite angle is equal
The diagonal is bisected by a longer diagonal
