In space, a reflection is a rigid motion that keeps all the points on one plane fixed, and flips all points to the opposite side of that plane. Note that if you perform any reflection twice, all points end up back where they started.
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.
