Homonym: 180° (Rotation)
The term "180°" refers to a specific angle measurement in geometry. It represents a straight line, as it is half of a full circle, which measures 360°. In practical terms, when an object rotates 180°, it turns to face the opposite direction.
In various contexts, such as navigation or sports, a 180° turn can signify a complete reversal. For example, in skateboarding, performing a 180° trick involves spinning the board and rider to land facing the opposite way. Understanding this angle is essential in fields like architecture and engineering, where precise measurements are crucial.
