- Definition
and properties of glide reflections
- Translations
and glide reflections are isometries because compositions of isometries
are isometries.
- Solving ab = cd for c or d. Notes
with solutions.
- Given 3 parallel lines m1, m2, m3, denote the reflections in these
lines by M1, M2, M3. The triple reflection M3 M2 M1 is a line reflection.
Construct the line n so that N, the line reflection in n satisfies N
= M3 M2 M1.
- Fundamental
Theorem 11: All isometries are compositions of 1, 2 or 3 line reflections.
- Fundamental Theorem 12: All isometries are translations, rotations,
line reflections or glide reflections (part of proof next time)
