This enjoyable activity comes from the Oswego City School District and was posted on
Jill Britton's excellent website. This activity may be used in geometry or calculus when
studying the concept of y-axis symmetry.
In most cases, the left side of a human face is close to being the mirror image of the right side. The first photo is the original photograph of my grandson James. The second and third photographs are composite pictures made by merging each side of the first picture with its corresponding reflection. If the line of symmetry is drawn through the center of each of the composite pictures, each point of the picture on one side of the line has an image point in the other side. The composite pictures are symmetric with respect to this vertical line. |

Using a digital camera, take photographs of the students in your class. Try to get the students to look directly at the camera. Using a photo-editing program or a drawing program, such as Adobe Photoshop or Paint Shop Pro, create composite drawings such as those shown above.
