Number of Lines of Symmetry

Introduction :

Symmetry is the one of the important topic in geometry. Symmetry means the image of the one part is equal to exact shape of another part.  That is we can cut the shape into exactly two parts.  Those two parts remains the same size and it is similar to the reflection of another part. In this topic we have to discuss about the number of lines of symmetry for each geometrical shape.
