In geometric terms, "true length" usually refers to the actual length of an object or line segment when viewed from an angle other than 90 degrees. It is particularly relevant in three-dimensional geometry and in fields like engineering and architecture, where accurate measurements are crucial. When dealing with projections or representations of objects, like in technical drawings or CAD (computer-aided design), true length ensures that the dimensions of an object are accurately represented, regardless of the perspective or view.
