Chords Arcs Proofs

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

Find the value of x. 14 and 18 represent the entire length of the chords

• √512

• √32

• √35

• √128
