Isometry is not only widely used to describe the motion of rigid bodies that is a mixture of rotational and translational motions of solids, but is also an important tool in theoretical physics and geometry. The properties of isometry have been actively researched for a long time, and this theory is widely used in fields such as natural science, computer engineering, radiology, imaging science, and design.
