๐Ÿ“š Quick Study Guide

  • ๐Ÿ“ A perpendicular bisector of a chord is a line that is perpendicular to the chord and passes through its midpoint.
  • โœจ If a line passes through the center of a circle and is perpendicular to a chord, then it bisects the chord.
  • ๐ŸŽฏ If a line bisects a chord and passes through the center of the circle, then it is perpendicular to the chord.
  • ๐Ÿ“ Congruent chords are chords that have the same length.
  • ๐Ÿ”„ In the same circle or congruent circles, if two chords are congruent, then their corresponding arcs are congruent.
  • ๐Ÿ“ In the same circle or congruent circles, if two arcs are congruent, then their corresponding chords are congruent.
  • ๐Ÿ”‘ Chords equidistant from the center of a circle are congruent. Conversely, congruent chords are equidistant from the center.
