If a 100 foot chord, laid out on the perimeter of the circle, subtends a 3 degree arc, then that curve is called a 3 degree curve. <br />An example: a circle of track with a 100 foot radius is pretty tight in real railroad terms. A chord of 100 feet laid out on the track would subtend 60 degrees (you'd have a equilateral triangle, too, as the legs from the chord extending to the center would measure 100 feet, also). <br />And that's the way it is. <br />Art
