Suppose we are given line segment (AB) ̅

We need to draw its copy

Let’s follow these steps

Draw a line
*
l
*

mark point P on it

- Measure line segment (AB) ̅ using compass

3. Now keeping compass opened the same length.

We keep pointed end at point P,

and draw an arc on line
*
l
*

*
*

So, the required line segment is PQ
