3. QUADRILATERAL TYPE OF SQUARE PARALLELOGRAM TRAPEZIUM

4. Types of Quadrilaterals A closed plane figure bounded by four straight lines is called a quadrilateral. A quadrilateral has four vertices. The line segments joining the opposite vertices are called its diagonals. A quadrilateral has 4 angles. The sum of its interior angles is 360 ⁰. 8

5. Special Kinds of Quadrilaterals Parallelogram: If the line segments in each pair of opposite sides of a quadrilateral are parallel, then the quadrilateral is called a parallelogram. Rhombus: If all the sides of a parallelogram are congruent, then it is called a rhombus. 9

6. Special Kinds of Quadrilaterals Rectangle: If all the angles of a parallelogram are right angles, then the quadrilateral is called a rectangle. Square: If all the sides of a rectangle are congruent, then it is called a square. Trapezium: If in a quadrilateral, line segments in one pair of opposite side are parallel and the opposite sides in the other pair are not parallel, then the quadrilateral is called a trapezium. 10

7. Special Kinds of Quadrilaterals-kite If in a quadrilateral, two pairs of adjacent sides are equal, then it is called a kite. The diagonals of a kite are not equal but intersect each other at right angles. 11

8. You have learnt A closed plane figure bounded by four straight lines is called a quadrilateral. The sum of the interior angles of a quadrilateral is 360 ⁰. If both pairs of opposite sides of a quadrilateral are parallel, then the quadrilateral is a parallelogram. If in a parallelogram, all sides are equal, then it is called a rhombus. If in a parallelogram, one of the angles is a right angle, then it is called a rectangle. If in a parallelogram, one of the angles is a right angle and all sided are equal, then it is called a square. 12
