• A quadrilateral in which both the pairs of opposite sides are parallel is called a parallelogram.
• A parallelogram one of whose angle is 90 degree is called a rectangle.
• a parallelogram whose all sides are equal and one of whose angle is 90 degree is called a square. A square is thus a rectangle having all sides equal.
• A parallelogram having all sides equal is called rhombus.
• A quadrilateral having one pair of opposite sides parallel is called trapezium.
• if two non parallel sides of a Trapezium are equal then it is called an isosceles trapezium.
• A quadrilateral in which two pairs of adjacent sides are equal is known as a kite.
