Section 11.2 Chords and Arcs Vocabulary Chord (p. 590) A chord of a circle is a segment whose endpoints are on the circle. Theorem 11-4 Within a circle or congruent circles (1) Congruent central angles have congruent chords. (2) Congruent chords have congruent arcs. (3) Congruent arcs have congruent central angles. Theorem 11-5 Within a circle or congruent circles (1) Chords equidistant from the center are congruent. (2) Congruent chords are equidistant from the center. Theorem 11-6
In a circle, a diameter that is
perpendicular to the chord bisect the chord and its arc.
Theorem11-7
In a circle, a diameter that bisects a
chord (that is not a diameter) is perpendicular to the chord.
