If we use the mnemonic that one turn is 360° or 2 radians, we can derive a formula for the transformation from degrees to radians. Because

3601=2 radians

this gives

1=2360 radians=180 radians.

Now we can start transforming the angles:

a)	45=451=45180 radians=4 radians,
b)	135=1351=135180 radians=43 radians,
c)	−63=−631=−63180 radians=−207 radians,
d)	270=2701=270180 radians=23 radians.
