Line of Reflection

Line of Reflection

Line over which a figure in a plane is reflected.


  • A reflection is denoted by the letter r.
  • The line of reflection, ℓ, is denoted by r.
  • If the line of reflection in the Cartesian plane is the x-axis, it is denoted by rx-axis. If the line of reflection is the y-axis, it is denoted by ry-axis.


In a reflection r with a line of reflection , the image of a point C is the point C‘ such that the segment CC’ is perpendicular to the line of reflection , and the midpoint O of CC’ is on the reflection line .
