**together**+ metron**measure**]## Reflection Symmetry

The simplest symmetry is Reflection Symmetry (sometimes called *Line Symmetry* or** ***Mirror Symmetry*). It is easy to see, because one half is the reflection of the other half.

The reflection in this lake also has symmetry, but in this case:

- the
**Line of Symmetry**runs left-to-right - it is not perfect symmetry, because the image is changed a little by the lake surface.

The Line of Symmetry does not have to be up-down or left-right, it can be in any direction. To learn more, go to Reflection Symmetry.

## Rotational Symmetry

With Rotational Symmetry, the image is rotated (around a central point) so that it appears 2 or more times. How many times it appears is called the **Order**.

Here are some examples (they were made using Symmetry Artist, and you can try it yourself!)

Order | Example Shape | Artwork |
---|---|---|

## Point Symmetry

Point Symmetry is when every part has a matching part:

- the
**same distance**from the central point - but in the
**opposite direction.**

*It is also the same as "Rotational Symmetry of Order 2"* above
