A POINT :-
                    A point is an idea which is represented by a small dot(.).It is named by a capital letter of the english alphabet . A point has no length , breadth and height.
 Example-   .

A LINE:-
                A Line has no ends points , it can be extended in both directions.

A line Segment:-
                               A line segment is a part of a line , it has a definite length and two end points.

A Ray
           A Ray is a line having an initially points which extends endlessly in the direction of the arrow like a ray of light.

PARALLELOGRAM:-
                                     1. Opposite sides of a parallelogram are equal.
2.Opposite sides of a parallelogram are parallel.

RHOMBUS:-
                      1. All four sides are equal.
2. opposite sides of a rhombus are parallel.

RECTANGLE:-
                         1. Opposite sides of a rectangle are equal.
2. Opposite sides of a rectangle are parallel.

SQUARE:-
                  1. All four sides are equal.
Opposite four sides of a square are parallel.

PENTAGON:-
                        1.Pentagon has five line-segments.
2. It has five vertices.

HEXAGON:-
                      1. Hexagon has six line-segments.
2.It has six vertices.

 PERIMETER:-
                          The sum of length of all the sides of a figure is called the perimeter.


CIRCLE:-
                A circle is a plane closed curved figure . All the objects given below are circles.

Note= A circle is named by its centre or the point from where the distance to any point on the circle is equal .The adjoining circle has a centre '0'.

Radius-
               A line segment which joins the centre of the circle to any point on the circle is called it's radius. In above circle , OA is radius of the circle . OB is also radius . Radius of the same circle are equal in length .So, OA=OB

DIAMETER:-
                        The diameter of a circle is twice the radius of the circle .It is the line that passes through the centre and divides a circle into two halves . POQ is the diameter .
