Glide Reflection, Rotational, Translation Symmetry

the composition of a translation followed by a reflection in a line parallel to the translation vector.

• glide reflection

• translation

• isometry

• composition of isometries

can be mapped onto itself using a rotation with a magnitude less than or equal to 180*

• rotational symmetry
