Lines passing through corresponding points of a figure set can meet at a fixed point {center of homothety} {center of similitude} {similitude center} {ray center} {homothetic center} {radially related figures}. Corresponding-point distances from ray center have constant ratio {homothetic ratio} {ray ratio} {ratio of homothety} {ratio of similitude} {similitude ratio}.
