Definition of glide reflection in English:

glide reflection

noun

Mathematics
  • A transformation consisting of a translation combined with a reflection about a plane parallel to the direction of the translation.

    • ‘Since translations and reflections are both isometries, a glide reflection is also an isometry.’
    • ‘The axes of the glide reflections aren't shown, but they are midway between parallel reflection axes.’
    • ‘There is an axis of a glide reflection without parallel axis of a reflection to it.’
    • ‘Because of this, we say the tiling is symmetric with respect to reflections and glide reflections.’
    • ‘Thus, the four symmetry operations are reduced to two operations - rotation and glide reflection.’
