There are several ways to study geometry .There is the clasical way which is basicaly graphicaly and intuitive .There is the other approach wich is based in a very strong foundation of vectorial algebra .This is really beatiful ,because it can be generalized to more dimensions than 3 . And is more elegant and precise
geometry is the best topic that i ever have, the application of this topis is universal,a lot of student of school of engineering have to learn this topic such us civil engineering. have fun with geometry, there are many links about it on the net.
you could find geometry fun to study:
1) if you develop a genuine interest in it. I've found all things are interesting if we really develop interest in them.
2)you'll need to master your trigonometry and all that, know about circles, polygons, quadriletrals - simple stuff!
3)put what you've learnt into practice.Judiciously.
