A tangent and secant are both special lines or segments that are created by intersecting or touching the points on the circle. They can intersect to develop a product such that the length of the square of the tangent segment is the product of the length of the external part of the secant...
Secant and Tangent Segments A tangent segment is a point of a tangent line between the point of contact and a point outside the circle. A secant segment is the part of a secant line that joins a point outside the circle to the farther intersection point of the secant and the circle. ...
The angle formed by the intersection of 2 tangents, 2 secants or 1 tangent and 1 secant outside the circle equals half the difference of theintercepted arcs! Therefore to find this angle (angle K in the examples below), all that you have to do is take the farintercepted arcand near th...
4.6 Tangent and Secant Additional subsidiary trigonometric functions can be defined in terms of sine and cosine. Consider just the first quadrant of the unit circle, redrawn in Figure 4.14. Let the horizontal line containing cosθ, as well as the hypotenuse, be extended until they intersect the...

A tangent to a circle is a line that intersects on the circle at one point. Most of the time, if a line that intersects a circle at one point, will also intersect it at a second point. To set it up very precisely, make the line intersect the circle at only one point so that it...
