When two tangent lines meet outside a circle, they create an external angle between them. The lengths of the segments from the points of tangency to the point where the tangents meet are equal, meaning the segments are equal in length. Additionally, the angle formed between the two tangents is equal to half the difference of the arcs that are intercepted by these tangents on the circle. This relationship illustrates the geometric properties that govern tangents and circles.

What is the relationship between the length of a tangent and a secant?
The relationship between the length of a tangent and a secant in a circle can be described using the tangent-secant theorem. According to this theorem, if a tangent segment is drawn from a point outside the circle to a point of tangency, and a secant segment is drawn from the same external point to intersect the circle at two points, then the square of the length of the tangent segment equals the product of the lengths of the entire secant segment and its external segment. Mathematically, if ( T ) is the length of the tangent and ( S ) is the length of the secant, the relationship can be expressed as ( T^2 = S \cdot (S - P) ), where ( P ) is the length of the part of the secant inside the circle.
True or false The measure of a tangent-tangent angle is half the difference of the measures of the intercepted arcs.?
True. The measure of a tangent-tangent angle is indeed half the difference of the measures of the intercepted arcs. This theorem applies to angles formed outside a circle by two tangents that intersect at a point, providing a relationship between the angle and the arcs it intercepts.

Definition of tangent in a circle?
A tangent to a circle is a line from a point outside the circles which touches the circle at a single point.
What is tangent in trigonometry?
Tangent is the ratio between perpendicular to the base of the triangle.
What is the relationship between a tangent line and a radius in a circle?
A tangent line is always perpendicular to the radius.
What is the relationship between the tan and cot?
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
What is the relationship between the tangents of complementary angles?
The tangent of an angle equals the inverse of an angle complementary to it. The relationship between the two tangents is that they are multiplicative inverses.
What happens between a radius and a tangent in a circle?
A tangent is always perpendicular to the radius of a circle. A radius is a straight line going from the center of the circle to the circumference (edge) of the circle. A tangent is a straight line outside the circle that touched the circle at one (and only one) point. When a tangent touches the outside edge of the circle at the same point where a radius touches the edge of the circle, the angle between the radius and tangent line is 90 degrees meaning they are perpendicular.
