Line Symmetry and Plane SymmetryVideos, worksheets, games and acivities to help Geometry students learn about line symmatry and plane symmetry.
Reflectional Symmetry Symmetry in a figure exists if there is a reflection, rotation, or translation that can be performed and the image is identical. Reflectional symmetry exists when the figure can be folded over onto itself along a line. This line is called the "line of symmetry". In regular polygons, the number of lines of symmetry equals the number of sides in the polygon.

Plane Symmetry Plane symmetry is analogous to line symmetry, except that it is in three dimensions. The three dimensional figure is divided into two halves by a plane. The following diagram shows a plane symmetry of a cuboid.
