I don't understand this: Describe the relationship of the segments made when chords intersect inside a circle. Use the following image as reference. http://curriculum.kcdistancelearning.com/courses/GEOMx-HS-WA10/b/assessments/C-ChordsandSecantsinCirclesQuiz/Geometry_7_1_13_Quiz_FINAL_4q.gif
Yeah there is a theorem that says the ratios of lengths of chords at point of intersection are same. X/W = Y/Z - I think. Not totally sure.
