👉 In geometry, a retation is a transformation that takes an object in one plane to another plane. This transformation can be performed by using a rotation matrix or a translation vector. A rotation matrix represents the orientation of an object in 3D space and acts as the basis for many geometric transformations. It has four elements: a row vector (a rotation angle), a column vector (the axis of rotation), a constant scaling factor, and a fourth element representing the position of the origin point.
