Aug 05, 2013 · Secant-Tangent: (whole secant) • (external part) = (tangent segment)2 b c a2 If a secant segment and tangent segment are drawn to a circle from the same external point, the product of the length of the secant segment and its external part equals the square of the length of the tangent segment By Mark Ryan . You can solve some circle problems using the Tangent-Secant Power Theorem. This theorem states that if a tangent and a secant are drawn from an external point to a circle, then the square of the measure of the tangent is equal to the product of the measures of the secant’s external part and the entire secant. Aug 05, 2013 · Secant-Tangent: (whole secant) • (external part) = (tangent segment)2 b c a2 If a secant segment and tangent segment are drawn to a circle from the same external point, the product of the length of the secant segment and its external part equals the square of the length of the tangent segment Secant-Secant Power Theorem: If two secants are drawn from an external point to a circle, then the product of the measures of one secant’s external part and that entire secant is equal to the product of the measures of the other secant’s external part and that entire secant.

Line a does not intersect the circle at all. Line b intersects the circle in two points and is called a SECANT. Line c intersects the circle in only one point and is called a TANGENT to the circle. a b c TANGENT/RADIUS THEOREMS: 1.

This concept teaches students to solve for missing segments created by a tangent line and a secant line intersecting outside a circle. This concept teaches students to solve for missing segments created by a tangent line and a secant line intersecting outside a circle. This concept teaches students to solve for missing segments created by a tangent line and a secant line intersecting outside a circle. Or, once in a blue moon, you might see the line just "touching" the circle, intersecting it at exactly one point. We have special names for these last two cases. If a line intersects a circle at two points, then the line is a secant of the circle. If a line intersects a circle at exactly one point, then the line is tangent to the circle. (You ...
