Segments of Tangents, Secants and Chords


Segments formed by tangents

Segments Formed by Tangents

Theorem

  • If two segments are tangent to a circle from the same external point, then the segments are congruent

Segments Formed by Secants

Theorem

  • If two secants intersect outside a circle, the product of the lengths of one secant segment and its external segment equals the product of the lengths of the other secant segment and its external segment.

  • (whole x outside = whole x outside)

Segments Formed by Secants

Theorem

  • If a secant and a tangent intersect outside a circle, then the product of the lengths of one secant segment and its external segment equals the length of the tangent segment squared.

  • (whole x outside = tangent squared)

Segments Formed by Intersecting Chords

Theorem

  • If two chords intersect inside a circle, then the product of the lengths of the segments of one chord equals the product of the lengths of the segments of the other chord.
