Similarity Transformations

A similarity transformation is a mathematical operation that changes the position, size, or orientation of a shape or object while preserving its overall proportions and structure. It involves scaling (resizing), rotating, and translating (moving) the object. Imagine resizing a photo while keeping its proportions, then shifting or rotating it to a different spot—these combined actions form a similarity transformation. It’s useful in geometry and computer graphics for comparing or manipulating shapes without distorting their fundamental properties.
