Reflection Symmetry


Reflection Symmetry is also called as Line Symmetry or Mirror Symmetry. One half of it is the reflection of the other half. 

  • The Line of Symmetryruns left-to-right
  • It is not a perfect symmetry, because the image is changed a little by the lake surface.

Line of Symmetry

The Line of Symmetry (also called the Mirror Line) can be in any direction.
But there are four common directions, and they are named for the line they make on the standard XY graph.
