1)make a line leaving space above
2)from one ending make a semi-circle
3)from that diameter only make 60 and 120 degree
for 30 degree
1)then bisect 60 and 0
2)the angle u will get will be 30
for 45 degree
1)bisect 60 and 30
2)the angle u will get will be 45
for 75 degree
1)first bisect 120 and 60,u will get 90
2)then bisect 60 and 90
3)the angle u will get will be 75
for 105 degree
1)bisect 60 and 120 for 90
2)bisect 120 and 90
3)the angle u will get will be 105
for 135 degree
1)bisect 120 and 180 to get 150
2)then bisect 150 and 120
3)the angle u will get will be 135
your angles r done
