Start at the top left dot and draw a diagonal line down to the bottom right dot, extending the line beyond the grid.
From the bottom right dot, draw a horizontal line to the left, extending it beyond the grid to connect the bottom left dot.
From the bottom left dot, draw a diagonal line up to the top right dot, extending the line beyond the grid.
Finally, from the top right dot, draw a horizontal line to the left, connecting the top middle and top left dots.
