But I wouldn't look for any connection more meaningful than that. When two secant lines intersect outside of a circle they form an angle on the exterior of the circle. To find the measure of the exterior angle, you need to know the measure of the two intercepted arcs. Those arcs fall between the two secants. One is large and one is small. The tangent to a circle is defined as a straight line that touches the circle at a single point.

The line is a secant because it intersects the circle twice. The blue line in the figure above is called the "secant to the circle c". As you move one of the points P,Q, the secant will change accordingly. If the two points coincide at the same point, the secant becomes a tangent, since it now touches the circle at just one point. The line segment inside the circle between P and Q is called a chord.

In words: the angle made by two secants (a line that cuts a circle at two points) that intersect outside the circle is half of the furthest arc minus the nearest arc. Why not try drawing one yourself, measure it using a protractor, and see what you get? It also works when either line is a tangent (a line that just touches a circle at one point).

In fact, these results are so useful that it is The perpendicular bisector of chord AC passes through the center O of the circle.

For any two secants, the product of the external segment and the whole length of the first secant is equal to the product of the external segment and the length of the second secant: secant, in mathematics. 1 In geometry, a secant is a straight line cutting a curve or surface. If it intersects the curve in two different points, as in the secant of a circle circle, closed plane curve consisting of all points at a given distance from some fixed point, called the center.
