Start with drawing of trigonometric circle (or you can find one in book or online).
Now that you have trigonometric circle in front of you, locate four main rays representing angles 0,π2,π,3π2.
Also, locate rays that represent angles π4,3π4,5π4,7π4.
If you located these rays, it is now simple to approximate an angle to the nearest π2. For example, if the angle is between rays that represent π4 and π2 we round that andle to π2.
