For outside you take two boards, lay one flat against the outside wall with a couple inches of the board extended beyond the corner. Place the other against the other wall on top of the first board. Mark the line with a pencil and voila, take a protractor, divide by two and you have the angle.

Inside miters are more of a pain, you have to create a set of setup blocks, but for inside you should be coping so the angle won’t affect the final cuts.

I’ve used Nathan’s method several times. If you don’t have a protractor, place the marked piece on the miter saw, eyeball the mark and line up the saw with it. when the saw matches the mark, you will know the angle. Then divide by 2 as Nathan said. The protractor would be easier though.

kent
you are right. I have used the saw like that many times.
If I don’t forget to bring the protractor I prefer it.
