**Introducation:-**

Geometry has a long and rich history. The term āGeometryā is the English

equivalent of the Greek word āGeometronā. āGeoā means Earth and āmetronā

means Measurement. According to

historians, the geometrical ideas shaped up

in ancient times, probably due to the need

in art, architecture and measurement. These

include occasions when the boundaries of

cultivated lands had to be marked without

giving room for complaints. Construction of

magnificent palaces, temples, lakes, dams

and cities, art and architecture propped up

these ideas. Even today geometrical ideas

are reflected in all forms of art,

measurements, architecture, engineering, cloth designing etc. You observe

and use different objects like boxes, tables, books, the tiffin box you carry

to your school for lunch, the ball with which you play and

so on. All such objects have different shapes. The ruler which you use, the

pencil with which you write are straight. The pictures of a bangle, the one

rupee coin or a ball appear round.

Here, you will learn some interesting facts that will help you know more

about the shapes around you.

By a sharp tip of the pencil, mark a dot on the paper. Sharper the tip, thinner

will be the dot. This almost invisible tiny dot will give you an idea of a point.

A point determines

a location.

These are some

models for a point :

If you mark three

points on a paper, you

would be required to

distinguish them. For

this they are denoted

by a single capital letter like A,B,C.

These points will be read as point A, point B and point C.

Of course, the dots have to be invisibly thin.

**A Line Segment:**

Fold a piece of paper and unfold it. Do you see

a fold? This gives the idea of a line segment. It

has two end points A and B.

Take a thin thread. Hold its two ends and

stretch it without a slack. It represents a line

segment. The ends held by hands are the end

points of the line segment.

The tip of a

compass

The sharpened

end of a pencil

The pointed end of

a needle.

The following are some models for a line segment :

Try to find more examples for line

segments from your surroundings.

Mark any two points A and B on a sheet

of paper. Try to connect A to B by all possible

routes.
