What is Symmetry?An object, shape or design can be said to be symmetrical if a line can be drawn through the middle, such that the two halves are mirror images of each other.

Lines of symmetry can be horizontal, vertical or diagonal.

For example, a butterfly has symmetry. If you drew a line down the middle of the butterfly, both sides would be the same.
