Student facing
are you ready for more?
finite figures, like the shapes we have
looked at in class, cannot have
translation symmetry. but with a pattern
that continues on forever, it is possible.
patterns like this one that have
translation symmetry in only one direction
are called frieze patterns.

1. what are the lines of symmetry for this pattern?
2. what angles of rotation produce symmetry for this pattern?
3. what translations produce symmetry for this pattern if we imagine it extending horizontally
forever?
