Hi PandaAdorable6990 !

Thanks for asking your question. :)

Sometimes, a figure needs to be made larger or smaller. When the final figure has the same proportions as the initial one, the transformation is called a dilation (also known as uniform scaling or homothety).

A dilation, denoted h (O,k) is a geometric transformation that makes it possible to enlarge or reduce a figure according to a scale factor k and a centre of dilation O.
