Question

find the angle of rotation of a pinwheel having 15 blades​

Answer 1

Answer:

The rotational symmetry of a shape explains that when an object is rotated on its own axis, the shape of the object looks the same. Many geometrical shapes appear to be symmetrical when they are rotated 180 degrees or with some angles, clockwise or anticlockwise. Some of the examples are square, circle, hexagon, etc. A scalene triangle does not have symmetry if rotated since the shape is asymmetrical. By the word symmetry, we know it is a combination of two words ‘sync+metry’. Hence, there should be at least two identical order to have symmetry.
