The steps of construction of an $$\angle AOB=45^{o}$$ is given in jumbled order below:
1. Place compass on intersection point.
2. Place ruler on start point and where arc intersects perpendicular line.
3. Adjust compass width to reach start point. 
4. Construct a perpendicular line.
5. Draw $$45$$ degree line.
6. Draw an arc that intersects perpendicular line. 
The third step in process is: 

The steps for constructing a line segment of given length are given in a jumbled order below:
1. Draw an arc on the line by keeping the pointed end of the compass on the point $$A$$. Mark the arc point as $$B$$.
2. Draw a line.
3. Extend the compass by keeping one end on the $$0\ cm$$ mark and other at the given length on the ruler.
4. Take a point $$A$$ anywhere on the line.

Which of the above steps comes first?

Construct a line segment of length 8.4 cm. Divide this line into 3 equal parts and find the length of each part.

Construct an angle of measure $$70^{o}$$, then half of that angle will be :

The angle made between the lines by drawing perpendicular bisector of a line segment is :
