About these units

Octant: An octant is one eighth of a full circle.It appears in geometry, navigation history, and spatial partitioning.

Straight angle: A straight angle is formed by two opposite rays lying on a straight line.It represents a half-turn and commonly appears in polygon geometry and directional reversals.
