Included angle in surveying

Webangle, ∆, intersects with the arc of the curve. LC is the long chord distance from the PC to the PT. The radius, R, is the distance from the arc to the center of the circle. The central angle is the same as the deflection angle measured at the PI from the back tangent (PC to PI) to the forward tangent (from PI to PT).
