The segment to which the constructed arc will be tangent at its start or end point.
The boolean indicating if the arc should be constructed at the start or end of the tangent segment.
The value indicating if the arc is oriented clockwise or counterclockwise.
The radius of the arc. Must not be equal to zero. If the radius is < 0, then the absolute value is used.
The length of the arc. Must not be equal to zero. If the arcLength is < 0, then the absolute value is used.
(Optional) The spatial reference of the arc. The default value is null.
