Answer:
Circles having equal radii are congruent.
Circles having different radii are similar.
The central angle which intercepts an arc is the double of any inscribed angle that intercepts the same arc (proof).
The radius perpendicular to a chord bisects the chord.
The chords equidistant from the center are equal in length.
