Materials: A print out of this worksheet


1. These pictures are found in the real world.

  • Draw the reflectional line of symmetry for each picture.
  • Are the lines of symmetry horizontal or vertical (Circle one)?

If the picture does not have any reflectional lines of symmetry, just write, no lines of symmetry!

2. How many reflectional lines of symmetry can you find in each picture?

If the picture does not have any reflectional lines of symmetry, state that.
