Mitre Angle Calculator
Enter an interior joint angle θ strictly between 0° and 180°. Two equal-width pieces lie in one plane and use symmetric cuts with no bevel. Cut-to-edge angle=θ/2; saw setting from a square cut=(180−θ)/2. A 90° corner gives 45° for both. This only computes planar geometry; it does not model compound cuts or tool calibration.
