Key concepts

3 concepts

  1. 1

    A glide reflection is a transformation that combines a translation and a reflection.

  2. 2

    Reflecting a shape over two parallel lines is the same as performing a translation, where the translation distance is twice the distance between the lines.

  3. 3

    Reflecting over two intersecting lines is the same as performing a rotation, where the rotation angle is twice the angle between the lines.

Quick comprehension check

Triangle MNP has coordinates M(1, 2), N(4, 2), and P(4, 5). Perform a glide reflection by translating the triangle 4 units to the left and then reflecting it over the x-axis. What are the coordinates of M''N''P'' after the glide reflection?
