WebAnswer. Recall that arcs formed by a pair of parallel chords are congruent. In the diagram, 𝐴 𝐵 and 𝐶 𝐷 are parallel chords, so the arcs formed are congruent. That is, 𝑚 𝐴 𝐶 = 𝑚 𝐵 𝐷 = 6 5 ∘. Next, since 𝐴 𝐵 is a chord that passes through the center of the circle, it is a diameter. Hence, the measure of arc ...
