an arc less than 180o

an arc greater than 180o

an angle whose vertex is the center of a circle

an arc exactly equal to 180o

measure of its central angle

360 - associated minor arc

Two minor arcs are congruent if and only if their corresponding chords are congruent

If a diameter of a circle is perpendicular to a chord, then the diameter BISECTS the chord AND its arc

(Similar to Fact #2) If one chord is a perpendicular bisector of another chord, then the first chord is a diameter

Two chords are congruent if and only if they are equidistant from the center
