*********POLYGON*********

Polygon:Any closed figure which three or more straight lines is called Polygon.

There are different types of polygon used in Mathematics applications and daily life.
Triangle:Triangle is a polygon which has three sides.

Quaderilaterals:Quaderilateral is a polygon which has four sides.

Square :Square is a polygon which has all sides equal and opposite sides parallel to each other
. Adjacent sides are perpendicular to each other.

Rectangle:Rectangle is a polygon which has equal and parallel opposite sides.Ajjacent sides are perpendicular to each other.

Rhombus:Rhombus is a polygon which has all sides equal and opposite sides parallel to each other.

Pparallogram :paralleogram is a polygon which has opposite equal and opposite sides parallel to each other
.

Trapezium: Trapezium is a polygon which has opposite sides parallel to each other


Kite: Kite is a polygon which has adjacent sides equal and opposite sides parallel to each other


********CHECK OUT SOLVED EXAMPLES********

1)Find the sum of interior angle of regular hexagon.
Ans: n=6,sum of of interior angles= (2n-4)*90
=(12-4)*90 =8*90=720 degree

check the answer!!!
2)Find exterior angle of regular heptagon
Ans: here n= 7,n=(360/n)
=360/7=51.45degree

check the answer!!!
3) Find the sides of polygon which exterior angle is 30 degree
Ans: exterior angle= 360/n,n=360/exterior angle=360/30 = 12
n=12

check the answer!!!
4.Check whether Polygon is possible or not
when the sum of interior angles is 3000degree

Ans:(2n-4)*90=3000

check the answer!!!
5)What would be the side of polygon whose interior angle is 30 degree
Let the side be n
(2n-4)*90=n*30
2n-4=(n*30)/90
2n-4=n/3,2n-n/3=4,5n/3=4,n=(4*3)/5=12/5
n should be natural number so polygon is not possible
check the answer!!!
6.Difference betFind p+q,p-q ,p=((2)1/2+2) /((2)1/2-2)),q = ((2)1/2-2) /((2)1/2+2))

Ans:
check the answer!!!
