Perpendicular Bisector Chords

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 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, the perpendicular bisector of a chord:

• is tangent to the circle

• is the diameter

• is a right triangle

• eats frosted flakes for dinner

Determine if the following expression is true or false. Why?

• The expression  $3x-4=5x-18$  is true because if a radius is perpendicular to a chord, it is the bisector of the chord and its arcs.
