  1. 10-7 Special Segments in a CircleN#____ 4/22-23/2014 SLG : Students will be able to find measures of segments that intersect in the interior and exterior of a circle.

  2. Chord Segments – Segments created when chords intersect in a circle. The products of these lengths are equal. 5 x+1 3 x x+10 6 10 x+8 If secant segments intersect outside a circle, then the product of one secant and its external secant will be equal to the product of the other secant and its external secant. 8 4 9 6 x 5 10 4

  3. If secant and a tangent intersect outside a circle, then the square of the tangent will be equal to the product of the secant and its external secant. 12 48 8 x 10 10
