Name the shapes and write down the number of lines of symmetry and order of rotation. Rectangle. 4 lines of symmetry, order of rotation 2. Parallelogram. 0 lines of symmetry, order of rotation 2. Triangle. 3 lines of symmetry, order of rotation 3. Octagon. 8 lines of symmetry, order of rotation 8. Hexagon. 6 lines of symmetry, order of rotation 6. Pentagon. 5 lines of symmetry, order of rotation 5.
