    Intersecting Chords

    Products of segments of intersecting chords are equal

     Intersecting Chords Theorem  

    Picture of product of intersecting chords rule

    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.
      A • B = C • D

    Practice Problems
    In the circle below, the chord segments have the following lengths: A= 6, C=3, D=4. Use the theorem for the product of chord segments to find the value of D.
     Answer
