pyörähdyssymetrisiä
Pyörähdyssymetrisiä refers to objects or shapes that exhibit rotational symmetry. This means that the object appears unchanged when rotated by a certain angle around a central point or axis. The degree of rotational symmetry is determined by the number of times the object can be rotated within a full 360-degree turn and still look the same. For instance, a square has rotational symmetry of order 4, as it looks identical after rotations of 90, 180, and 270 degrees, in addition to the original position.
The order of rotational symmetry is often denoted by 'n'. An object with rotational symmetry of order
In nature, rotational symmetry is observed in many forms, such as the petals of flowers, the arrangement
