CHAPTER+9.5+T.O

SEGMENTS OF TANGENTS, SECANTS, AND CHORDS.
objectives: 1. Define special cases of segments related to circles, including secant-secant, secant-tangent, and chord-chord segments 2.Develop and use theorems about measures of the segments


 * __DEFINTIONS AND BLUE BOXES:__**


 * THEOREM 1-** If two segments are a tangent to a circle from the same external point, then the segments
 * THEOREM 2-** If two secants intersect outside a circle, the product of the lengths of one secant segment and its external segment equals
 * THEOREM 3-** If a secant and a tangent intersect outside a circle, then the product of the lengths of the secant segment and its external segment equals . (whole x outside = tangent squared)
 * THEOREM 4-** If two chords intersect inside a circle, then the product of the lengths of the segments of one chord equals _?

lets try to find the diameter! use the theorem 3 d x 5 = 10 squared d x 5 = 100 d = 500!
