Take a piece of paper. Fold it in half. Spill a few drops of ink on one half side. Now press the halves together. What do you see? Is the resulting figure symmetric? If yes, where is the line of symmetry? Is there any other line along which it can be folded to produce two identical parts? Try more such patterns.

Take a square piece of paper. Fold it into half vertically, fold it again into half horizontally. (i. e., you have folded it twice J. Now open out the folds and again fold the square into half (for a third time now), but this time along a diagonal, as shown in the figure. Again open it and fold it into half(for the fourth time J, but this time along the other diagonal, as shown in the figure. Open out the fold. How many lines of symmetry does the shape have?
