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.
Definition of an exterior angle. At each vertex of a triangle, an exterior angle of the triangle may be formed by extending ONE SIDE of the triangle. See picture below. Calculating the Angles. We can use equations to represent the measures of the angles described above. One equation might tell us the sum of the angles of the triangle. For example, x + y + z = 180. We know this is true, because the sum of the angles inside a triangle is always 180 degrees. What is w? We don't know yet. But, we may observe that the measure of angle w plus the measure of angle z = 180 degrees, because they are a pair of supplementary angles.
