How It Works

The miter angle for any regular polygon is 180 / n, where n is the number of sides. For a 4-sided picture frame, set your miter saw to 45 degrees. For a hexagonal planter, set it to 30 degrees. Most miter saws have positive stops at common angles. Always cut test pieces from scrap before cutting your project wood.
