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°
