Angle preservation

Angle preservation refers to maintaining the original angles between lines or shapes when they are transformed or changed in size, position, or shape. For example, if you rotate or scale a geometric figure without distorting its angles, the angles between its sides stay the same. This concept is important in various fields like geometry, computer graphics, and engineering, where ensuring that the original relationships within a structure are kept intact during modifications is crucial. Essentially, angle preservation keeps the "sharpness" or "corner" qualities of a shape unchanged, even as its size or orientation changes.
