Good morning (at least it is morning here...)

From time to time, there have been posts here about paper models, so I'm
hoping that at least a few of you are experienced wnough with them to help
me out with this one...

What is the math involved to lay out a "flat" piece for a roof that when cut & assembled, will have a certain amount of slope to it? If I laid the roof out flat for a 90° corner, then tried to put some slope to it, the angle that the two pieces formed would be something less than 90°. I'd like to know the math involved so that I can figure roof slope on ANY angle that I might encounter. This has to be pretty easy, but I'm stumped.

Anyone know?

Thanks.
