The line through that same point that is perpendicular to the tangent line is called a normal line. We will call that point T. As you draw tangent lines to the more straightened part of the parabola, it might become harder to see that the line only touches the parabola at a single point. Sag curves are used where the change in grade is positive, such as valleys, while crest curves are used when the change in grade is negative, such as hills. Find the point of tangency P. Determine where the curve has horizontal tangents. A tangent never crosses a circle, means it cannot pass through the circle. That point is called the point of tangency.
