It is very simple to draw the angle of 45. We
just bisect the angle of 90.

We have learnt all the major angles and how to
draw remaining ones. TIPS for the remaining ones
are here.
For 75, cut an arc from 60 and another one from
90. You will get the desired angle.
For 105, cut the arcs from 90 and 120.
For 150, use 120 and 180 likewise
For 115,you need to choose 120 and 150
