Reflection in the x-axis. A reflection in the x-axis can be seen in the picture below in which A is reflected to its image A'. The general rule for a reflection in the x-axis: (A,B) (A, âB) Reflection in the y-axis. A reflection in the y-axis can be seen in the picture below in which A is reflected to its image A'.
A reflection is called a rigid transformation or isometry because the image is the same size and shape as the pre-image. The reflection line, m, is the perpendicular bisector o f the segments joining each point to its image. Notice that these segments are parallel, since they are perpendicular to the same line.
