angle measurement
Quantifying corner sharpness
Angle measurement is the determination of how much one line or surface diverges from another, typically expressed in degrees, radians, or gradians.
A full rotation equals 360 degrees or 2π radians.
Tools like protractors and theodolites measure angles in geometry, navigation, and surveying: The angle measurement showed the roof pitched at 30 degrees.
