    I think if: 1. Chords are = distance from center they are congruent. and 2. Congruent chords are = distance from center.

    Ok. That's what I figured. We need to use the Pythagorean Theorem to find the radius of the circle. Also we need to remember that a radius that is perpendicular to the chord bisects the chord.

    What you posted is true, however, the chords in your picture are not the same length are they?
