1. 10.7 Special Segments in a Circle
Two Chords
seg1 x seg2 = seg1 x seg2
Two Secants
outer segment x whole secant =
outer segment x whole secant
Secant and Tangent
outer segment x whole secant = tangent squared
*Add the segments to get the whole secant

2. E D A F
2 chords:
AO x OB = DO x OC
2 secants:
EF x EG = EH x EI H O C I B G

3. A D
Secant and Tangent:
AD x AB = AC x AC C B
