6. A "tiling" of the plane occurs when we fill the entire, infinite plane with a repeated pattern. The image to the right shows a portion of one such tiling. The pattern extends forever in all directions. (a) Give all angles of rotational symmetry between 0 and 360° about the two marked points. Point A: Point B:

(b) Draw and label line m such that m is neither horizontal nor vertical and is a line of reflective symmetry of the tiling.
