Chords equidistant from a circle's center are congruent and form a 90° angle; they are parallel and out of phase.
Congruence: Any two chords that are the same distance from the center of a circle are congruent. This means they have the same length.
Perpendicularity: The radius bisecting an angle at the center of a circle is perpendicular to the chord that subtends the angle, meaning they form a 90° angle between each other.
Parallelism: These chords are parallel to each other and out of phase.
