Task# Finding Lines of Symmetry

Illustrative MathematicsVaries

The purpose of this task is for students to identify figures that have line symmetry and draw appropriate lines of symmetry. If students are first learning about symmetry, it would be good for them to create their own line-symmetric shapes by folding a piece of paper in half and cutting a shape out. Then they can darken the line represented by the fold to reinforce that it is a line of symmetry for their shape. Identifying the lines of symmetry gets increasingly complex for the figures in part (a).
