Screw Euclid. Get a modern interpretation like Jacobs "Elementary Geometry".
Euclid is great for historical reasons, but modern methods are far more efficient. Not the mention you get practice problems with books. Einstein didnt use Euclid; he too used a modern interpretation by some German author.
If you insist on Euclid,make it this one: http://www.amazon.com/Euclids-Elemen.../dp/1888009195
