The segment to which the constructed arc will be tangent at its start or end point.
The value indicating if the arc is oriented clockwise or counterclockwise.
The boolean indicating if the arc should be constructed at the start or end of the tangent segment.
The chord length of the arc. If the chord length is < 0, then the absolute value is used.
