An oval has two lines of symmetry. A line of symmetry is defined as the line that a figure can be divided into half, with the end result of the two halves matching up exactly. Each side of the divided side looks like a mirror image. Comments.
A Reflectional Symmetry is a type of symmetry in which one half of the object is the mirror image of the other. 1  A figure may have both horizontal and vertical lines of reflection. 2  The alphabet V has reflectional symmetry about a vertical line of reflection.  The hexagon has reflectional symmetry about both horizontal and vertical lines of reflection.
