Question

write the order of rotational symmetry and draw angle of rotation​

Answer 1

When the hands of a clock go round, we could say that they rotate. The hands of a clock rotate in only one direction, about a fixed point, the centre of the clock-face. Rotation, like movement of the hands of a clock, is called a clockwise rotation; otherwise it is said to be anticlockwise. If you spin the wheel of a bicycle, it rotates. It can rotate in either way: both clockwise and anticlockwise.

When an object rotates, its shape and size do not change. The rotation turns an object about a fixed point. This fixed point is the centre of rotation. ..
