Draw an impossible triangle by drawing an equilateral triangle and chopping off its corners. This will leave you with a hexagon with three long, and three short sides. Draw a smaller equilateral triangle in the middle of that hexagon. Then draw a line from one corner of the hexagon until it just passes the small triangle. Extend one side of that triangle to meet the other line and repeat for the other two sides. When you are done, it should look like there are three L’s fitted together to form a 3D triangle with a triangular hole in the middle.
