3. QUADRILATERALS

4. QUADRILATERALS
A four sided closed figure are called
Quadrilaterals.

5. Different Types of Quadrilaterals
Parallelogram
Rectangle
Square
Rhombus
Trapezium
Isosceles Trapezium

6. PARALLELOGRAM
Parallelogram is a quadrilateral
where each pair of opposite
sides are parallel. So in parallelogram
The opposite sides are equal
The opposite angles are equal
The diagonals bisect each other

7. RECTANGLE
A rectangle is a parallelogram
in which each angles is a
right angles. So in a rectangle
Opposite sides are equal
Opposite sides parallel

8. SQUARE
A square is a rectangle in
Which each angle is a right
angles.
So in a square
All four sides are equal
Opposite sides are parallel
The diagonals are equal

9. RHOMBUS
A rhombus is a parallelogram
in which all four sides are equal.
So in a rhombus
Opposite sides are parallel
All sides are equal
Opposite angles are equal
Diagonal bisect each other at
right angles.

10. TRAPEZIUM
In a Trapezium only one
pair of opposite sides are
parallel and no angles are
equal.

11. ISOSCELES TRAPEZIUM
In an Isosceles Trapezium, two
opposite sides are parallel and other
two sides are equal.
