Circles and Length of Segments:
Theorem:
When two chords intersect inside a circle, the product of the
lengths of the segments of one chord is equal to the product of
the lengths of the segments of the other chord.
Theorem:
When two secant segments are drawn to a circle from a point
outside the circle, the product of the lengths of one secant
segment and its outer segment equals the product of the lengths
of other secant segment and its outer segment.
Theorem:
When a secant segment and a tangent segment are drawn to a circle from
a point outside the circle, the product of the length of the
secant segment and its outer segment is equal to the square of
the length of the tangent segment.
