      Let the vertex of an angle be at the origin, with one side of the angle on the positive x-axis. The radian measure of the angle is a measure of the intercepted arc length on a circle of radius 1. To convert between degree and radian measure, use the fact that π radians — 180° = 1. Writing Radian Measures of Angles Work with a partner.

The total deflection (DC) between the tangent (T) and long chord (C) is ∆/2. The deflection per foot of curve (dc) is found from the equation: dc = (Lc / L)(∆/2). dc and ∆ are in degrees.
