(Im)Possible Shape?
Can you draw this shape without lifting your pencil off the page or crossing any lines?
Hint - Yes, it is possible. You just have to pick the right starting point and path. Can you see why some starting points won't work?
Some intersections have 3 lines coming together, some of four. Is there some rules you can see regarding the number of lines that are coming together at any point?
