Lots of code. Creating modules

[Lux]

When you import a module, it has different functions within it. If you look at your usage of the math module, you are using math.sqrt, not just sqrt. You should do the same thing with your imports from the geometry module, like this: geometry.myfunction()

Also, please use code tags next time you post. Just put [python] before the code, and the same thing with /python after it.
