# how to really start learning some three-dimensional geometry [closed]

I am neither a mathematician nor a maths major student. More likely, I am a dumb person in mathematics especially in three- dimensional geometry. I can’t draw an acceptable diagram and apply theorem to proof any questions in my homework. I tried to find a way to became an “average person”, but I failed. My question is : are there any books , videos o, classes in college or whatever start to talk about some basic problems in three- dimentional geometry and develop the basic understanding of it? I don’t need any answer like “ I am sorry that’s so bad” or “there are some courses in college talking about geometry, such as 304 or 415.” I am hearing these for years! The question seems quite weird posting here. Give me your suggestions if you don’t mind to reduce your maths taste.

To give advice, it would help me if I knew your motivation to learn math. The term "three-dimensional geometry" has many possible interpretations. And I think your difficulty in understanding 3d-geometry courses indicates you might start learning another (easier) part of math first. –  Konrad Voelkel Nov 8 '09 at 22:25

I'm not sure what you mean with three-dimensional geometry, but if you mean geometry of curves and surfaces in $\mathbb{R}^3$ I would recommend you

Differential Geometry of Curves and Surfaces, by Manfredo Do Carmo .

Judging from the rest of the post it's quite likely the OP means something more basic. –  Qiaochu Yuan Nov 9 '09 at 4:00
