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 $$. 1. Draw 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?
