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.
The minimum order of rotational symmetry a shape can have is 1. The order of rotational symmetry of a regular polygon is equal to the number of sides. There are six special quadrilaterals with different symmetrical properties. A square has four lines of symmetry.
