30-degree angle
One-twelfth full rotation
A 30-degree angle is one-twelfth of a full rotation, or one-third of a right angle.
In geometry, it appears as one of the acute angles in a 30-60-90 triangle, a common reference shape.
The term describes any angle measuring exactly thirty degrees: The ramp rises at a 30-degree angle.
