Symmetry

• Symmetry is when a shape or object has two completely identical sides that are either facing each other or are around an axis.

• A line of symmetry is the line that divides the two identical parts, each part being a mirror reflection of the other.

Lines of Symmetry

• You are going to get some shapes stapled together.

• We will be folding these shapes to create lines of symmetry.

• You will be recording how many lines of symmetry each shape has on here.
