It can help in so many ways, trust me, you might not think so now, but if using angles and stuff is what your doing, (for using canvas lines to create a seamless 3D effect), or what ever it is your doing, i advise you visit the site to learn a little bit of trigonometry

So, I don't know anything about trigonometry. And I want to know, how to check if...

1. two lines cut eachothers?

2. a point is inside a triangle?

Could you post it in trigonometry? And if possible, post it in python.
I think I'd be able to convert it to python, altrough I don't know trigonometry.

If I'm asking ridiculous things, could you post me a link to a site where are python scripts like those?

And no fries with that this time, thanks.
