45° Angle
1 Draw the angle of 90° as learned before. Draw arcs from point n and o respectively and
join the cut point to A.
n P
45°
It is very simple to draw the angle of 45°. We just bisect the angle of 90°.

14. 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°
