Слайд 6
Polygon :
A simple closed figures by joining three or more
line segments is called polygon
Lets study about types of polygons
Слайд 7Triangle :
It is a closed figure formed by joining three
line segments . So , a triangle is a polygon . Different shapes of triangle are shown below:
The three line segments which form the triangle are called its sides .
The three line segments which form the triangle are called its sides .
Слайд 8Quadrilateral :
It is a closed figure formed by joining four
line segments called quadrilateral. So quadrilateral is a polygon. Different shapes of quadrilateral are shown below:
The four line segments which form a quadrilateral are called its sides.
The four line segments which form a quadrilateral are called its sides.
Слайд 9Circle :
A closed curve formed in such a way that
any point on this curve is equidistant from a fixed point which is in the interior of the curve.
A

C
Слайд 11Center:
A fixed point in the interior of
circle whose distance from all the points on the circle is same.
A
B
C
D
O
OA = OB = OC = OD
Слайд 12Radius:
The distance between the center and any point on the
circle is called the radius of the circle.
AAAA
A
A
O
Слайд 13Diameter :
The line which passes through the center and meet
any two points on the circle is called the diameter.
A
B
A diameter is twice the length of radius.
O
Слайд 14Chord :
The line which meet at any two points on
the circle .
A diameter is the longest chord of a circle.
CD is the chord of the circle.
A diameter is the longest chord of a circle.
CD is the chord of the circle.
A

Слайд 15Circumference :
Length of a closed curve forming the boundary
of the circle is called the circumference of the circle.
