Mitering Inside Corners. 1  1. Measure the angle of the corner. 2  2. Set a compound miter saw with the correct angles. 3  3. Cut the right inside corner.  4. Set the miter saw angle 1  again. 5. Cut the left inside corner.  6. Fit the two pieces together before nailing them in place.
There are a couple of different tools that you can use to miter corners and what you can use will depend on what you're cutting and how it needs to be cut. Basic, standard cuts can be done on simple materials using a miter box and a hand saw.More complex cuts will need a circular or table saw.f your mitered corner is at the standard 45 degree angle((360/2)/corners), then you'll need a gap at the end equal to the depth of the piece of wood. 1  If you're using a non-45 angle, you'll need to do some math.
