Geometry and Spatial Sense: Symmetry

Symmetry: an object is symmetric with respect to a line if each point has a corresponding point the same distance on the other side of the line. The line is often referred to a line of symmetry.

For example, the following picture can have a line of symmetry drawn where each point on one side has a corresponding point on the other side.
