Draw a straight line AB = 6.5 cm. Draw another line which is parallel to AB at a distance of 2.8 cm from it.
Steps of construction :
1. Draw a straight line AB = 6.5 cm
2. Taking point A as centre, draw an arc of radius 2.8 cm.
3. Taking B as centre, drawn another arc of radius 2.8 cm.
4. Draw a line CD which touches the two arcs drawn.
Thus CD is the required parallel line.
