Overview
Compare translation, rotation, and homothety images.
Explanation
Translation: every point moves the same vector — shape and size fixed.
Rotation: turn about a fixed point by a fixed angle — shape and size fixed.
Homothety (scaling): rays through a center, parallel corresponding sides, fixed similarity ratio — shape fixed, size may change.
How to use
Switch transform type, adjust parameters, drag the original; dashed figure is the image.
