Sketch the figure below.

Fold the paper along the line, so that your drawing is on the outside, then trace the figure on the opposite side of the line. When you unfold the paper, the new image forms a figure with a line of symmetry.

Look in the yellow pages of your local phone book for company logos that have lines of symmetry.

Find a crossword puzzle and determine by folding if it has a line of symmetry.
