Geometry
Look at the tiny dot in the middle of this box. .
A dot like this is called a
A point has
It only has a
If you bring many such dots each other in a chain, you will get a
Hence, a line is made up of many points.
Points, Lines and Line Segments
Here is a line:We write line AB as
A line is always drawn with arrows on both sides. This indicates that a line has no starting or ending points.
The part of the line between
A line segment has a starting point and an ending point. It has a fixed length. It can be drawn by joining two pints with a scale.
We can measure the length of a line segment with a scale.
The line segment between A and B is called line segment Ab and is written as AB
