What is the angle of rotation of alphabet S
A triangle can be rotated through any angle of your choice!An equilateral triangle has rotational symmetry of order 3, which means that a rotation of 120 degrees (or multiples) will bring it back to the same orientation. All other triangles have rotational symmetry of order 1: that is, you have to rotate them a full circle (360 deg) before they look the same.
right...Each corner of a square is called a "right angle" and measures 90 degrees with a protractor.a 90o angle, also called a right angle
The least angle at which the figure may be rotated to coincide with itself is the angle of symmetry.

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 ...
The square has 4 sides and has rotational symmetry of order 4. Also, the angle rotation measurement is 90 degrees.
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.
Yes. An isosceles triangle, for example, is symmetric about the bisector of its odd angle but has no rotational symmetry.

None.
What is the angle of rotation of alphabet S
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:
Assuming the question is about ROTATIONAL symmetry rather than rational symmetry, the answer is none.
It is 360 degrees divided by the order of rotational symmetry.
Because if you rotate it about its center it looks different (not symmetric) no matter what the angle is.
Sometimes called rotation symmetry, or symmetry of rotation. If you have an object that can be turned through a certain angle (like rotating a cube through 90o) and then it looks identical, then that object has a certain symmetry under rotation. If you can turn it through any angle, like a cylinder, then it has rotation (or rotational) symmetry.
