Leading/Lagging!

[Masterspongebob]

Hey guys, thanks in advance for all your help!



Please look at my picture above where there is a 3 angle picture; V1 is actually 270 degrees, V2 is 0 degrees, and v3 is 60 degrees.

Point of origin is 0 degrees. Now, no matter how much my professor explains to me, I just do not get it. I do not get how V1 lags behind V3 by 150

degrees. Shouldn't V1 lead V3 by a total of 210 degrees? Thanks for your input guys!

You are saying the same thing in two different ways. However,just as a matter of convention by some, the lead/lag is done for the smaller value, thus given the choice of lead by 210 or lag by 150, since 150 is smaller, it is lag by 150. What do you do about 180? Flip a coin I guess.
