Homothetic transformation

In mathematics, a homothety (or homothecy, or homogeneous dilation) is a transformation of an affine space determined by a point S called its center and a nonzero number k called its ratio, which sends point X to a point X′ by the rule, SX′→=kSX→{\displaystyle {\overrightarrow {SX'}}=k{\overrightarrow {SX}}} for a fixed number ⁠k≠0{\displaystyle k eq 0}⁠.
