Review thetwo basic types of symmetry: Bilateral Symmetry Symmetry in which a shape can be folded along an imaginary line (axis of symmetry) so that opposite sides of the shape match Also called reflectional symmetry Examples include insects, animals, reflections in ponds Rotational Symmetry Symmetry in which a shape can be rotated around its center point so that it looks like its original self Also called radial symmetry Examples include snowflakes, flowers, starfish
