Baskets and Circles

I saw this basket that was holding oranges in my house and realized that it had an interesting design on it. The diameter is splitting the circle in half creating two congruent arcs. The other two chords in the circle share the same central angle. This means that the arcs would be congruent based off theorem 9-3, which is that if arcs share central angles then they are congruent. the chords would also be congruent because congruent arcs have congruent chords.
