![]() ![]() In the above diagram, PQR is a triangle with coordinates of the vertices P(-1, -3), Q(-4, -1), and R(-6, -4). In the above diagram, translation (glide) performed on the foot, and then reflection across the parallel line of translation, then again glide followed by the refection, this foot steps are the typical example of glide reflection. In everyday life, a classic example of glide reflection is the track of footprints left in the sand by a person walking over it. Reflection in y = -x: (x, y) → (-y, -x).Therefore, we have to use translation rule and reflection rule to perform a glide reflection on a figure. Glide reflection is a composition of translation and reflection. Midpoint (midpoints remains the same in each figure) is preserved in a glide reflection.Collinearity (points stay on the same lines) is preserved in a glide reflection.Perpendicularity is preserved in a glide reflection.Parallelism is preserved in a glide reflection. ![]()
