QuoteEven if the lines are thicker than the dots you can still achieve the answer I provided. That was simply the best way of drawing it on a PC.

Even if you extend the left line through the top-left dot, you'll be dissecting that dot into 4 pieces, not two equal halves. You could argue that that single line dissects it into equal halves, but then the other two lines going into it are not, and it would still fail your specifications.
