Re: accurate angles
I thought about this for several minutes and then came up with this. So as you can imagine, I haven't tried it.
Set your T-bevel to the angle of the corner. Transfer this to a piece of paper; cut it out so the cut edge of the paper fits into an inside corner, or around an outside corner.
Now fold the paper in half starting at the corner and mating the cut edges that touch the wall; the angle between the edge and the fold will be the angle to set you miter saw at.
Works for both inside and outside corners, but outside corners might take a little more thinking. No math necessary; no need to know how many degrees the corner is.
