Problem: Within the square, draw a line to connect from box A to the other box A, then draw a line from box B to the other box B, and box C to box B. There should not be any intersections.
Connect 6 Boxes Without Crossing Lines
Draw a line interfacing the two boxes marked A. Define another boundary interfacing the crates marked B. Define a third boundary interfacing the crates marked C. The lines can’t cross. The lines can’t go past the limits of the square shape walling them in. [Note: The lines don’t need to be straight.] There’s not much or disillusioning with regards to the arrangement.
