The delta angle is used to make other relevant calculations, or it can be determined using known measurements. A delta angle is the measurement in degrees where two straight lines, also known as tangents, intersect. A horizontal circular curve is a mathematical calculation determining the optimal arc between two tangents. The measurement of the central curve on the arc is equal to the delta angle.
10 r (x, y) Î¸ O y x. Definition 2.1: Trigonometric Functions of a General Angle Let Î¸ be an angle in standard position and suppose that (x, y) is any point other than (0, 0) on the terminal side of Î¸ (Figure 2.3).s Figure 2b shows, an angle of â187Â° is a quadrant II angle. If the terminal side of an angle in standard position lies along either the x axis or the y axis, then the angle is called quadrantal. For example, â360Â° , â270Â° , â180Â° , â90Â° , 0 Â° , 90 Â° , 180 Â° , 270 Â° , 360 Â° are quadrantal angles.
