I saw a project posted that had multiple miter angles. There were LJs asking about what the angle settings were. To answer their questions I’m posting here.
Angles for any shape. Divide number of desired sides into 360. Divide the answer of that equation by 2. That is the setting number of degrees of miter to cut. This method does not apply to equally to trapezoids.
For five point star because there are 20 cuts, the miter angles are 72° & 36° at the ends of each piece. These are the angles from alternating sides of the piece cut.
For a pentagon it takes 5 pieces to form the shape. Take the 72° angle and divide in half equaling 36°. Because there are only 5 pieces, 10 cuts to make a pentagon. The 36° angle is applied from the same side of the piece.
Hope this makes sense to those interested.
