Itâs a cost-benefit analysis: If it costs you 3 hours weekly to do the wash, but costs you $30 to send it out â that is $10 per hour. But if you bill more than that at your business â or stand to get a raise if you use those three hours to learn new skills, earn a degree, etc., it is worth the investment.
Coordinate Rules for Rotations. In general, we can state the following coordinate rules for (counterclockwise) rotations about the origin: For a rotation of 90o: (x, y) --> (ây, x) For a rotation of 180o: (x, y) --> (âx, ây) For a rotation of 270o: (x, y) --> (y, âx)
Thus, we conclude that rotational symmetry of rhombus is at 180 degrees and at 360 degrees. Thus we say that the order of symmetry of rhombus is 2. In case of rhombus, we find that the order of rotation of figure is 2. Therefore, the angle of rotational symmetry = 360 / order of symmetry = 360 / 2 = 180 degrees. It means that after the rotation of every 180 degrees, the rhombus will take its original shape.
