Geometry Honors. What and Why. What?. Find the lengths of chords and measures of arcs of a circle.. Locate the center of a circle using chords.. Why?. To find the radius of a circle in real-life situations such as archaeology.. 9.4. Theorem. In the same circle, or in congruent circles:. Congruent arcs have congruent chords .. Congruent chords have congruent arcs. . Theorem. A diameter that is perpendicular to a chord bisects the chord and its arc. . Chords. Although there are many types of chords and chord qualities. , we will focus on the basics; Triads and Seventh chords.. Triads are 3 note chords stacked in 3rds.. Root, 3. rd. , 5. th. . I-3-5 C-E-G.
