**Line of symmetry - Math**
https://www.math.net/line-of-symmetry

Mathematically, a line of symmetry is a line of reflectionthat maps any point on the figure back to the figure. The line that cuts through the major axis of the ellipseabove is a line of symmetry. When A and B are reflected across it, they are mapped to A' and B', also on the ellipse. This is true for any point on the ellipse. Not all lines of reflection are also lines of symmetry just …
