Regular Polygon Calculations

Calculate across corners (outer diameter), across flats (inner diameter) or side length for regular polygons with any number of sides from three up. The polygon can be anywhere from a triangle, square, hexagon, octogon, to one with a maximum number of sides that depends upon the capacity of the user's computer.
(Note that if you'e dealing with a triangle it would be better to use the trigonometry calculator application in Trades Math Calculator.)
Also calculated is the included angle of the corners, which can be converted from Degrees decimal to Degrees-minutes-seconds.
All linear values can be converted between inches and millimeters.
