If I can be given a hint on how to start, I will try to figure this out.. Add a comment 2 Answers WebA diameter is a chord containing the circle’s center. To prove that a chord is a diameter you must show that it contains the center. Two arbitrary congruent chords may or may not contain the center. If they both contain the center, then they are both diameters. Let’s consider the case of two congruent chords that do not contain the center:
