If the contact between the template and bonnet rear reference line is tangential and the point of tangency lies outside the arc scribed by points ‘C' and ‘D', then the bonnet rear reference line is extended and/or modified to follow the circumferential arc of the template to meet the bonnet side reference line, as shown in Figure 9. So, you find that the point of tangency is (2, 8); the equation of tangent line is y = 12x – 16; and the points of normalcy are approximately (–1.539, –3.645), (–0.335, –0.038), and (0.250, 0.016). A line drawn from the point of tangency to the centre of the disc is called a normal, and the tangent makes an angle of 90° with the normal.

You can use either the point-slope form or the two-point form to arrive at y = 12x – 16. What is the abbreviation for Point of Tangency? The exact point of tangency (see FIG CC) is where a straight line intersects the beginning of curvature of travel is the point labelled "EC". At the point of tangency any radius forms a right angle with a tangent. The tangent line to a curve at a given point is the line which intersects the curve at the point and has the same instantaneous slope as the curve at the point.
