A curve is a part of the arc of a circle. It is limited at each end by the radii of the circle which form a central angle at the center of the circle. Curves are described by the following terms: A. Radius is the distance from a point on the curve to the center of the circle. B. Length. of curve is the linear measurement of the curve. C. Concavity

This gets the central angle for any amount of sides we want. Try it. Central Angle 4. Good, now we have a way to get the central angle. Let's use it to find half the side of the polygon. HalfSide =: sind @ CentralAngle NB. Find sin after finding the central angle. Side =: Halfside * 2: NB. Get the Side Length
