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.

  • Центр подобия (или центр гомотетии) — это точка, из которой по меньшей мере две геометрически подобные фигуры можно видеть как масштабирование (растяжение/сжатие) друг друга. Если центр внешний, две фигуры похожи друг на друга прямо — их углы одни и те же в смысле вращения. Если центр внутренний, две фигуры являются изменёнными в размерах отражениями друг друга — их углы противоположны.
