Which edition of Harold Jacobs Geometry?

[dovrar]

I'm trying to figure out which edition of Harold Jacobs Geometry to buy. Any suggestions?

 

Thanks so much!

I'd use the 3rd edition, which is what Harold Jacobs recommended even years after writing the third ed, but it probably doesn't matter much.  I know a lot of people here like the 2nd.  With the 3rd, you can use it either as a discovery approach or not.  My DS doesn't like a discovery approach; we used it as a non-discovery approach and he really liked Jacobs 3rd ed but probably would have liked the second ed too; we never tried the 2nd ed.
