Four straight-line segments of length \(\ell\) lie in a plane and do not cross. One end of segment 1 is connected to one end of segment 2 such that they form a \(30^{\circ}\) interior angle. The other end of segment 2 is connected to one end of segment 3 , also forming a \(30^{\circ}\) interior angle. Finally, the other end of segment 3 is connected to one end of segment 4 , forming another \(30^{\circ}\) interior angle. What is the distance between the unconnected ends of segments 1 and 4 ?
