All lines of action pass through one point. Angles are measured anticlockwise from the positive horizontal (→), 0–360°. The diagram labels each angle to the nearest horizontal, as in textbook figures.

Supports at each end (A at 0 m, B at the far end). Up to 4 point loads and 2 UDLs. Positions are measured from A.
Angle is measured from the beam on the right-hand side: 90° acts straight down, 60° leans to the right, 120° leans to the left.
