| has gloss | eng: In geometry, a homothetic center (also called a center of similarity or a center of similitude) is a point from which at least two geometrically similar figures can be seen as a dilation/contraction of one another. If the center is external, the two figures are directly similar to one another; their angles have the same rotational sense. If the center is internal, the two figures are scaled mirror images of one another; their angles have the opposite sense. |

| has gloss | fin: Homotetiakeskus on yksi euklidisen geometrian peruskäsitteistä. Sitä voidaan kuvailla samankaltaisuuden tai vastaavuuden keskukseksi. Homotetiakeskus on piste, josta vähintään kaksi geometrisesti samanmuotoista kuviota voidaan nähdä suurempana tai pienempänä suhteessa toisiinsa. Termiä käytetään myös yleisesti analyyttisessa geometriassa. |
