Using a protractor, draw an angle of measure `72^@dot` With this angle as given, draw an angle of measure `36^@dot`

Explanation

Steps of construction:

1. Draw an angle ABC of `72^@` with the help of protractor.

2. With center B and any radius, draw an arc which intersect AB at D and BC at E.

3. With center D and E and radius more than`( DE)/2`draw two arcs which intersect each other at F.

4. Join FB which intersect the arc in (2) at G.

5. With centers D and G and radius more than `(DE)/2` draw two arcs which intersect each other at F.

6. With centers D and G and radius more than `(DG)/2` draw two arcs which intersect each other at H.

7. Join HB.
