There are three types of symmetry:
1. Reflection Symmetry -
A line of symmetry divides the figure in half, and the two halves are mirror images of each other. The image of the heart below is an example of reflection symmetry. If the heart is folded along the vertical line, the two halves coincide with each other.
2. Rotation Symmetry -
A figure is turned around a fixed center point and aligns with the original image. The image of the star below is an example of rotation symmetry. If the star is turned, it appears to be the same shape. If the star is turned 5 times, it returns to its original position.
3. Translation Symmetry -
A figure is slid left, right, up, down, or diagonal and remains the same shape. The image of the lightning bolt is an example of translation symmetry. The shape does not change, but rather is moved in space.
