The document discusses symmetry and lines of symmetry. It defines symmetry as an attribute of a shape where there is an exact reflection of form on opposite sides of a dividing line. A line of symmetry is described as a line that divides a figure into two halves that are mirror images of each other. Examples of objects and nature photos are provided to identify lines of symmetry.

2. What is Symmetry An attribute of a shape exact reflection of form on opposite sides of a dividing line

3. Line of Symmetry Line symmetry line that divides a figure into two halves that are mirror images of each other

4. Which object has symmetry ? Look at each object Decide which one has two halves that are mirror images of each other Draw the line of symmetry on your choice

5. Which object has symmetry ? Look at each object Decide which one has two halves that are mirror images of each other Draw the line of symmetry on your choice

6. Symmetry Yes or No? Look at each object Decide if it has symmetry? Select green check for YES Select red ‘x’ for no

7. Symmetry Yes or No? Look at each object Decide if it has symmetry? Select green check for YES Select red ‘x’ for no
