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:
Magnetic meridian
The angle of the satellite period, depends on where the satellite is positioned. When you figure out where the satellite is you position the angle to be where and what you need.
23.5 degrees, the same as the "tilt" of Earth's rotational axis in space, the cause of the seasons.
Take any one point on the figure. Draw a line from it to the origin. At the origin measure an angle of 90 degrees (right angle) in a clockwise direction. Draw a line from the origin at this new angle and of the same length as the original angle. Repeat this process for the other points in the figure. NB Be careful, there will be numerous lines from the origin. At the end points of the new lines, connect up to reveal the origin figure ,but rotated 90 degrees - clockwise.
Closest to farthest from the Sun Hottest to coldest (or coldest to hottest) Smallest to largest (or largest to smallest) Most to least dense Least to most atmosphere With and without rings With and without moons (or least to most number of moons) By the angle of tilt of their axes Basically, by any of the major physical or chemical propoerties of the planets.

the line of symmetry from the middle
None. You can rotate a circle by the smallest possible angle that you can think of and it will be an angle of symmetry. And then you can halve that angle of rotation and still have rotational symmetry. And you can halve that angle ...
45
It is 360 degrees divided by the order of rotational symmetry.
Yes. An isosceles triangle, for example, is symmetric about the bisector of its odd angle but has no rotational symmetry.
The square has 4 sides and has rotational symmetry of order 4. Also, the angle rotation measurement is 90 degrees.
None.
What is the angle of rotation of alphabet S
A "pure" trapezoid (a pair of parallel sides and two random sides) does not have rotational symmetry. If it is a parallelogram then it has a 180 degree symmetry. And if the paralloelogram happens to be a square, you have 90 deg symmetry.
Assuming the question is about ROTATIONAL symmetry rather than rational symmetry, the answer is none.
The least angle at which the figure may be rotated to coincide with itself is the angle of symmetry.
Because if you rotate it about its center it looks different (not symmetric) no matter what the angle is.
