to go around a center point is to rotate

### How do you find the smallest angle of rotational symmetry for a figure?

If you can rotate (or turn) a figure around a center point by fewer than 360° and the figure appears unchanged, then the figure has rotation symmetry. The point around which you rotate is called the center of rotation, and the smallest angle you need to turn is called the angle of rotation. This figure has rotation symmetry of 72°, and the center of rotation is the center of the figure:

### Find the location of the center of mass of the earth-moon system.?

If Earth has 81 times the mass of the Moon, you must find a point between the two, from which the Moon is 81 times farther than the Earth. That is, divide the distance from the center of the Earth to the center of the Moon by 82. The point at that distance from the Earth's center is the center of mass. I understand this point is still within the Earth. This point will change…

### Where is acupuncture zero point?

Point Zero is on the auricle (fleshy part of the ear). Specifically, it is found in the center of the ear, where the helix (outside ridge) curves around back to the center of the ear. Point Zero is located at the end of this ridge. For a visual map, see: http://www.yinyanghouse.com/theory/auricular/acupuncture_chart

### Why does a claw hammer rotate when tossed?

Certain objects will rotate when thrown because they are rotating around a pivot point, this pivot point is the center of gravity. A baseball, tennis ball, et cetera won't rotate because it's center of gravity is at the center of the ball. A baseball bat, hammer, et cetera will rotate because it has its center of gravity at the heavier end.
