Diameter of a Circle Is Perpendicular to a Chord

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

In  a circle, if a radius or diameter is perpendicular to a chord, then it____ the chord and its arc.

• equals

• bisects

• arcs

• circles

In the diagram, the diameter of the circle is perpendicular to a chord. Solve for the value of "x" and "y"

• x = 4, y = 5

• x = 3, y = 7

• x = 7, y = 3

• x = 6, y = 9
