rigidliikumised
Rigidliikumised refers to a category of geometric transformations that preserve distances between points. In essence, they are movements that do not distort or change the shape or size of an object. Imagine a rigid body in physical space; any movement it undergoes without deformation is a rigidliikumine. The set of all possible rigidliikumised in a given space forms a mathematical group under composition.
The fundamental types of rigidliikumised in Euclidean geometry are translations and rotations. A translation shifts every
In two-dimensional Euclidean space, any rigidliikumine can be expressed as a combination of at most one translation
