Chord Chord Angle

In a circle (or congruent circles), chords that are the same distance from the center:

• are similar

• have the same name

• are congruent to each other

• are walking dead

In a circle, if a diameter is is perpendicular to a chord, then:

• it bisects the chord

• it bisects the corresponding arc

• it bisects BOTH the chord and its arc

• none of these answers are correct

In a circle, if a diameter bisects a chord (that is not a diameter), then:

• it is a secant

• it is parallel to the chord

• it is perpendicular to the chord

• it is just shaking out the sillies
