Circle Theorems for Arcs and Chords:

1. If two chords are congruent, then their corresponding arcs are congruent.2. If the diameter or radius is perpendicular to a chord, then it bisects the chord and its arc.

3. In the same circle or congruent circles, two chords are congruent if and only if they are equidistant from the center.

Arcs and Chords

This video will demonstrate the above three theorems and how they may be used.

Using Chords Equidistant From the Center This geometry video math lesson deals with circle geometry. The main focus of this video is using the Chords Equidistant from the Center of a Circle Theorem. The theorem states: chords equidistant from the center of a circle are congruent and congruent chords are equidistant from the center of a circle.

This lesson takes a look at chords and arcs and the theorems associated with them and the circles that they are a part of. Few examples are worked out.
