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.
If the left angle measures 145 degrees, then the angle that is opposite it also measures 145 degrees. Another property of vertical angles is that angles that are next to each other are supplementary angles, meaning that they add up to 180 degrees. So, if one angle measures 35 degrees, then the angle that is directly to the left or right will measure 145 degrees, since 35 + 145 is 180. Using Vertical Angles. To use the identifying property of vertical angles, you just need to know the measurement of the angle that is opposite the angle that is missing the measurement. So, if your missing angle is the bottom angle, all you need to know is the measurement of the top angle. If the top angle measures 60, then so does the bottom angle.
