This document contains information about different types of quadrilaterals: 1) It defines a quadrilateral as a plane figure with four sides and four vertices. It can be represented as ABCD. It discusses types of quadrilaterals including trapezoids which have one set of parallel sides, and parallelograms which have both pairs of opposite sides parallel. 2) Properties of different quadrilaterals are provided, including parallelograms having opposite sides equal and angles, rectangles having four right angles and equal sides, squares having four equal sides and right angles, and rhombus having four equal sides. 3) Kites are defined as having one pair of equal adjacent sides and unequal opposite

4. Q Draw the graph of equation 2x+y=6. find
the co-ordinate of the point, where graph
cut the x-axis. Shade the region bounded by
the graph & the co-ordinate of axis.
1) which is the shape form?
2)find the area of shape formed?

5. 2x+y=6
y=6-2x
if x=1
then, y=6-2(1)=4
if x=2
then, y=6-2(2)=2
if x=3
then, y=6-2(3)=0

7. 1) It is a triangle
2)Base of triangle:3 units
height of triangle:6 unit
area of triangle=1/2 x base x height
=(1/2 x 3 x 6)units
=9 sq . units

9. The word ‘quad’ means four &
the word ‘lateral’ means sides.
thus,
a plane figure bounded by four
line segments AB,BC,CD&DA is
called a quadrilateral & is
written as quad.ABCD or
ABCD. The point A,B,C,D are called its vertices. The four
line segment, AB,BC,CD,DA are the four sides, and the four
angels <A,<B,<C,<D are the four angles of quad. ABCD.
Two line segments AC&BD are called the diagonals of quad.
ABCD.

10. A quadrilateral having exactly one
pair of parallel sides, is called a
trapezium.
ABCD is a trapezium in which
AB||CD. A

11. >its two sides are parallel.
>its diagonal are not equal.
>sum of all angles is 360 degrees.

12. A quadrilateral is a parallelogram if its
both pairs of opposite sides are parallel.

13. >A diagonal of a parallelogram divides it
into two congruent triangles.
>in a parallelogram, opposite sides are
equal.
>the opposite angles of angles of a
parallelogram are equal

14. > The diagonal of a parallelogram bisect
each other.
>in A parallelogram, the bisectors of any
two consecutive angles intersect at right
angles
> if diagonal of a parallelogram bisects
one of the angles of the parallelogram, it
also bisects the second angles.

15. A parallelogram whose each angles is a
right angle, is called a rectangle.

16. >its all angle are of 90 degrees.
>its opp. Sides are equal & parallel.
>its diagonal are equal & bisect each
other.
>its diagonal cut each other at 90
degrees.

17. A parallelogram whose each angles is a
right angle and each sides are equal, is
called a square.

18. >it’s each sides and each angles are
equal .
> its diagonal are equal to each other
and bisects each other at 90 degrees .
>its opp. Sides are parallel to each
other.

19. A parallelogram with equal sides is
known as rhombus.

20. >Rhombus has equal sides.
>it’s opposites angles are equal.
> it’s diagonal bisect each other.
> it’s diagonals cut the rhombus into two
congruent triangles.

21. A quadrilateral is a kite if it has pair
of equal adjacent sides & unequal
opposite sides

22. >it have a pair of equal angle &
unequal angles.
>it have unequal diagonals.
>its longer diagonal always cut the
kite into two congruent triangles.
