In this sectionwe gainedmoretoolsto find the lengthof chordsand the measureof arcs.We learnedthat
the perpendicularbisectorof a chordis a diameterand that the perpendicularbisectorof a chordalso bisects
the correspondingarc. We found that congruentchordsare equidistantfromthe center, and chords
equidistantfrom the centerare congruent.
