Types of Symmetry Reflection: the figure can be divided into two parts that are mirror images of each other Reflection: the figure can be divided into two parts that are mirror images of each other Rotation: a figure coincides with its original position when turned about a point Rotation: a figure coincides with its original position when turned about a point Translation: a figure coincides with its original position when it is moved right, left, up, down, or any combination of these directions Translation: a figure coincides with its original position when it is moved right, left, up, down, or any combination of these directions Any combination of the above Any combination of the above
