SYMMETRY ALL AROUND US

For more information regarding this activity and its objectives, see the accompanying Teacher's Guide.

For each of the following pictures, examine the photo carefully and respond to the corresponding questions.

1. Ignoring the reflections in the windows, use a colored marker to show where this photo could be folded so that the two halves match.

From now on we will refer to this fold as the line of reflection. You have just sketched the line of reflection with respect to the entire photo.

• What shape is repeated to create this window? Sketch this basic shape and show its lines of reflection.

• Compare the lines of reflection with respect to the entire photo to the lines of reflection of the basic shape.

• What simple shape is repeated to make this window? Sketch it and show its lines of reflection.

• Explain how the lines of reflection with respect to the entire photo would be different if the center rectangle was filled with squares instead.
