What is measure of arc WG?

• 90

• 30

• 150

• 120

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

A tangent line intersecting with a radius always creates a ____________ angle

• right

• acute

• obtuse

• straight
