Congruent chords theorem In the same circle or in congruent circles: 1. Congruent arcs have congruent chords 2. Congruent chords have congruent arcs

Congruent chords theorem cont.

Diameter A diameter that is perpendicular to a chord bisects the chord and its arc

Arc/chord Bisector

In the same triangle or congruent triangles: 1. Chords equally distant from the center (or centers) are congruent. 2. Congruent chords are equally distant from the center (or centers).
