An Infinite Number
multiply the coordinates by -1.
360 degree rotation (clockwise or anticlockwise) leaves any figure in exactly the same position as it was at the start. So YOU DO NOTHING.
Imagine a clock: a circle is 360 degrees, so every 5 minutes is 30 degrees. If you started at 1pm and rotated it 90 degrees it would be 1.15pm
Copernicus proved that the earth is flat and that we are NOT the center of all the universe. He also proved that planets rotate around the sun. He was also a well respected astronomer.
A circle contains 360 degrees. Draw a circle, add a radius to any point on it, and then rotate the radius completely around. After it has returned to the point it initially intersected the curve, the radius will have rotated through 360 degrees.(another explanation, maybe no better.)A complete circle measures 360 degrees, so a half-circle is 180 degrees, a quarter-circle is 90 degrees and so forth. Another way to look at it is in terms of the central angle formed by the radii drawn from each endpoint of the arc - the measure of the arc in degrees is the same as the measure of this central angle in degrees.
Every place.
Infinitely many. A circle is symmetrical in infinitely many ways as well.
A circle is the set of all the points that have the same distance from a given point (its center). If you rotate a shape, you rotate it in such a way that you keep any point a fixed distance from the center of rotation.

Yes, a circle has infinite rotational symmetry. This means that no matter how much you rotate a circle about its center, it will look the same at every angle.
infinite! as much as you rotate it , it will be exactly the same arent circles cool ? (:
180o is half a circle (semi-circle). To rotate do the following: 180 + 180 = 360o
Because the center of the fan is attacked to something, and if the fan is relatively rigid, other points on the fan keep the same distance from that center. The set of points in a plane that has the same distance from the center is called a circle.
Green circle. (For Microsoft Office 2010.)
rotate
To turn around a centre point is to rotate.
24 hours {1 day} to rotate 1 year {exactly} to make a full circle around the sun {Orbit}
