a Pattern A: 1 line of symmetry Open: design own circle and line pattern.
Pattern B: no line of symmetry
Pattern C: no line symmetry
Pattern D: no line symmetry
b Pattern A: no rotational symmetry
Pattern B: rotational symmetry of order 2
Pattern C: rotational symmetry of order 2
Pattern D: rotational symmetry of order 3
Open: design a circle pattern and write about its symmetries.
