Symmetry: It is a quality of
some shapes which some of their parts are reflections of others.
Reflection symmetry: It is a shapes quality which is formed by two halves facing each other with an axis or fold line in between as if both sides where a mirrror images of each other.
Symmetry axis: It is a line which divides a shape into two symmetric halves. Symmetric points are on a perpendicular line to it.
Central symmetry: It is the reflection of an object through a point called the symmetry center. Symmetric pair of points are colinear with the center.
