Is This Puzzle Possible? You have to in 1 continuous line go though ALL lines on there without passing through 1 twice.. And the places where lines intersect counts as a new line segment starting there so yeah. Like there are 4 lines in the middle. 3 lines on bottom. Is it possible?

Are you sure this is not possible? My teacher told me it was but yet again he is a genius..

>> No.3611312

>>3611282
It's impossible. The shapes on the top left, top right and bottom middle have 5 sides each. Think about what happens when you cross all lines of an odd-sided shape. If you start from the outside, you will finish on the inside. If you start on the inside, you will finish on the outside. Therefore, the line must begin or end in an odd-sided shape. The line has only 2 ends, but there are 3 such shapes.

That's the most concise way I can think to explain it.

Touching a line segment at the end is not the same as passing through it. "Through" implies that there's something of the line segment on both sides of where you're passing. By your definition you go through a building if you walk by alongside it, touching the wall with one hand.
